Question: What is the unit of currency in the country that has the After the Morning performer as one of its citizens?

full_context: Document 1: British Isles: There are two sovereign states in the isles: Ireland and the United Kingdom of Great Britain and Northern Ireland. Ireland, sometimes called the Republic of Ireland, governs five sixths of the island of Ireland, with the remainder of the island forming Northern Ireland. Northern Ireland is a part of the United Kingdom of Great Britain and Northern Ireland, usually shortened to simply the United Kingdom, which governs the remainder of the archipelago with the exception of the Isle of Man and the Channel Islands. The Isle of Man and the two states of the Channel Islands, Jersey and Guernsey, are known as the Crown Dependencies. They exercise constitutional rights of self-government and judicial independence; responsibility for international representation rests largely upon the UK (in consultation with the respective governments); and responsibility for defence is reserved by the UK. The United Kingdom is made up of four constituent parts: England, Scotland and Wales, forming Great Britain, and Northern Ireland in the north-east of the island of Ireland. Of these, Scotland, Wales and Northern Ireland have "devolved" governments meaning that they have their own parliaments/assemblies and are self-governing with respect to certain areas set down by law. For judicial purposes, Scotland, Northern Ireland and England and Wales (the latter being one entity) form separate legal jurisdiction, with there being no single law for the UK as a whole.
Document 2: Hill of Thieves: Hill of Thieves is the fourth solo album by Irish folk singer Cara Dillon. It is her first full-length release on Charcoal Records, the label formed in 2008 with her musical partner and husband Sam Lakeman. The album was recorded and produced by Sam and first became available in October 2008 at their live concerts. It is also the first release since she gave birth to their twin boys Noah and Colm at 26 weeks, after going into labour onstage at the Swindon Arts Centre, UK. It has been the most successful of her first four albums in relation to chart performance, entering at No. 7 in the UK Indie Album Charts (see below for more.)
Document 3: There's More Where That Came From: There's More Where That Came From is the sixth studio album by Lee Ann Womack, released in 2005. It received numerous awards and critical acclaim and was also Womack's highest selling album since 2000's "I Hope You Dance". The album was Womack's return to a traditional country music style, producing three charting singles between 2004 and 2006: "I May Hate Myself in the Morning", "He Oughta Know That by Now" and "Twenty Years and Two Husbands Ago", which peaked at numbers 10, 22, and 32, respectively, on the Hot Country Songs charts. Womack's ex-husband, Jason Sellers, sang background vocals on "I May Hate Myself in the Morning".
Document 4: Cadore 33: Popular Spanish singer Sergio Dalma followed 2011's four-times platinum "Via Dalma II" with "Cadore 33." Unlike Dalma's previous two albums, which consisted of Spanish-language covers of Italian songs, this marked his return to performing original material.
Document 5: A Girl Called Dusty: Dusty Springfield had been a member of the girl group The Lana Sisters from 1958 to 1960, and the folk-pop trio The Springfields from 1960–1963, in the latter case with her brother Tom Springfield. While on tour in the US in the early 1960s she was exposed to soul music, which was to have a profound impact on her subsequent life and career. Although The Springfields were moderately successful, with songs such as "Island of Dreams", "Bambino" and "Silver Threads And Golden Needles" (a No. 16 US country hit), their style of music limited the wide range of material that Dusty Springfield wanted to sing. Therefore, in 1963, Springfield decided to begin a career as a solo singer.

Document 7: Never in a Million Years (Cara Dillon song): "Never In A Million Years" is the lead single release from After The Morning, the third album by Cara Dillon. The single was released as a promo for radio stations in the UK and Ireland. The single was also released exclusively by iTunes as a digital download a week prior to the release of "After the Morning", where it climbed to #39 in the iTunes Top 100.
Document 8: Saint Helena: Today Saint Helena has its own currency, the Saint Helena pound, which is at parity with the pound sterling. The government of Saint Helena produces its own coinage and banknotes. The Bank of Saint Helena was established on Saint Helena and Ascension Island in 2004. It has branches in Jamestown on Saint Helena, and Georgetown, Ascension Island and it took over the business of the St. Helena government savings bank and Ascension Island Savings Bank.
Document 9: Cara Dillon: Cara Elizabeth Dillon (born 21 July 1975, Dungiven, County Londonderry, Northern Ireland) is an Irish folk singer. In 1995, she joined the folk supergroup Equation and signed a record deal with Warners Music Group. After leaving the group, she collaborated with Sam Lakeman under the name Polar Star. In 2001, she released her first solo album, "Cara Dillon", which featured traditional songs and two original Dillon\Lakeman compositions. The album was an unexpected hit in the folk world, with Dillon receiving four nominations at the 2002 BBC Radio 2 Folk Awards.
Document 10: After the Morning (Cara Dillon album): "After the Morning" is the third solo album from folk artist Cara Dillon. It was recorded at their home studio in Frome, Somerset, Mayfair, Kore, Amberville and Sun Street Studios. The strings and brass were recorded in Prague. Similar to her previous albums, "After the Morning" was produced by Sam Lakeman, her husband and musical partner. Additional production was by Mike 'Spike' Drake, who also mixed the album. The album features the singles "Never in a Million Years", and the double A-side of "I Wish You Well" and "This Time".
Document 11: One pound (British coin): The original, round £1 coin replaced the Bank of England £1 note, which ceased to be issued at the end of 1984 and was removed from circulation on 11 March 1988, though still redeemable at the Bank's offices, like all English banknotes. One - pound notes continue to be issued in Jersey, Guernsey and the Isle of Man, and by the Royal Bank of Scotland, but the pound coin is much more widely used. A new, dodecagonal (12 - sided) design of coin was introduced on 28 March 2017 and both new and old versions of the one pound coin circulated together until the older design was withdrawn from circulation on 15 October 2017. After that date, the older coin could only be redeemed at banks, although some retailers announced they would continue to accept it for a limited time. The original round pound remains legal tender on the Isle of Man.
Document 12: Early Hours: Early Hours is Eleanor McEvoy's fifth studio album. The style of this album differs from her previous work with its collection of songs incorporating many musical styles including folk, jazz, and blues. The album features McEvoy on vocals, guitar and fiddle. Album co-producer Brian Connor accompanies her on piano, Hammond, and a variety of keyboards. Also featured on the album are drummer/percussionist, Liam Bradley, Calum McColl on guitar, bassist is Nicky Scott, and Lindley Hamilton on trumpet. "Early Hours" was the first album to use TiMax (unique audio imaging) technology, mixed in 5.1 surround sound onto multi-channel super audio compact disc Super Audio Compact Disc (SACD).
Document 13: Carly Simon: After a brief stint with her sister Lucy Simon as duo group the Simon Sisters, she found great success as a solo artist with her 1971 self-titled debut album "Carly Simon", which won her the Grammy Award for Best New Artist, and spawned her first Top 10 single "That's the Way I've Always Heard It Should Be". She achieved international fame with her third album "No Secrets" which sat firmly at No. 1 on the "Billboard" 200 for five weeks and spawned the worldwide hit "You're So Vain", for which she received three Grammy nominations, including Record of the Year and Song of the Year. With her 1988 hit "Let the River Run", from the film "Working Girl", she became the first artist to win a Grammy Award, an Academy Award, and a Golden Globe Award for a song composed and written, as well as performed, entirely by a single artist.
Document 14: Thinking Out Loud: In the kitchen, Sheeran and Wadge began writing the song at 2: 00 am on 4 February 2014, and completed it in 20 minutes. According to Wadge, the lyrical content resulted from her and Sheeran's talking about ``everlasting love '', inspired by the circumstances relevant at that time. Sheeran also revealed that the lyrics were inspired by his then - girlfriend, Athina Andrelos, whom Sheeran met in early 2014. Sheeran would later explain that he wrote the song`` in a relationship at a really, really happy point''. Immediately after writing, Sheeran recorded the song on his phone. He was keen to include ``Thinking Out Loud ''on the second album. He properly recorded the song the following day at the Sticky Studios, a recording facility located in the small Surrey village of Windlesham, and informed Wadge of its inclusion on the album. It became the last song recorded for the album. For`` Thinking Out Loud'', Sheeran sought the assistance of Jake Gosling, who produced much of his debut album and had earlier contributed tracks, four of which appear on the standard version of the second album.
Document 15: Pound sterling: The British Crown dependencies of Guernsey and Jersey produce their own local issues of sterling: the ``Guernsey pound ''and the`` Jersey pound''. The pound sterling is also used in the Isle of Man (alongside the Manx pound), Gibraltar (alongside the Gibraltar pound), the Falkland Islands (alongside the Falkland Islands pound), Saint Helena and Ascension Island in Saint Helena, Ascension and Tristan da Cunha (alongside the Saint Helena pound). The Bank of England is the central bank for the pound sterling, issuing its own coins and banknotes, and regulating issuance of banknotes by private banks in Scotland and Northern Ireland. Banknotes issued by other jurisdictions are not regulated by the Bank of England; local governments use Bank of England notes as backing for local issuance by allowing them to be exchanged 1: 1 at face value.
