Folk rock group Fairport Convention is usually credited as the first English electric folk band.
 Founded in 1967 and initially covering songs by artists such as Bob Dylan and Joni Mitchell, they developed a devoted niche following by providing electrified and upbeat versions of traditional folk tunes alongside with their own compositions.
 In a career spanning over forty years, notable for numerous changes of line-up as well as continued success, Fairport Convention have issued over fifty albums.
Fotheringay was a short-lived British folk rock group, formed in 1970 by singer Sandy Denny on her departure from Fairport Convention.
 The band drew its name from her 1968 composition "Fotheringay" about Fotheringhay Castle, in which Mary, Queen of Scots had been imprisoned.
 The song originally appeared on the 1969 Fairport Convention album, "What We Did on Our Holidays", Denny's first album with that group.
 There have been live performances by a band formed by three of Fotheringay's surviving members with other musicians in 2015 and 2016.
Towie Barclay Castle is a historic castle in Aberdeenshire, Scotland, 4.5 miles south-south-east of Turriff.
 The current structure was built in 1593 by Clan Barclay.
 The site was given to the Clan in the 11th century by Malcolm III of Scotland.
 Following Clan Barclay's pillage of a nunnery in the 12th century, Thomas the Rhymer proclaimed: "Towie Barclay of the Glen/Happy to the maids/But never to the men."
, which was interpreted as a curse on the male line.
 Belief in the curse was strong enough that it was given as a reason by Mr. Barclay Maitland for the sale of Towie Barclay Castle in 1753 to the Earl of Findlater, who, after "dreeing the weird," (the <nowiki>"</nowiki>weird<nowiki>"</nowiki>, meaning the curse) and after his son also died, sold it to Gordon's Hospital in Aberdeen in 1792.
Later That Same Year is the 1970 album by country rock/folk rock musician Ian Matthews' band, Matthews Southern Comfort.
 This was Ian's third album after his departure from Fairport Convention in 1969, and was released in November 1970 shortly after the band's single "Woodstock" had reached Number One in the UK singles chart.
 For the US release in Spring 1971, "Jonah" was left off the album and was replaced with "Woodstock" which became the lead track.
Marc Ellington (born 16th December 1945, Boston, Lincolnshire) is a musician, with links to Fairport Convention and Matthews' Southern Comfort, who currently resides in Towie Barclay Castle in Aberdeenshire, Scotland.
Second Spring is the 1970 album by country rock/folk rock musician Ian Matthews' band Matthews' Southern Comfort.
 It was Matthews's second album after his departure from Fairport Convention and was recorded with the touring band he put together following the release of his first solo LP, "Matthews' Southern Comfort".
 It was released on the Uni label in July 1970.
Fairport Convention is Fairport Convention's debut album.
 The band formed in 1967, with the original line-up consisting of Richard Thompson (guitar), Simon Nicol (guitar), Ashley “Tyger” Hutchings (bass), and Sean Frater (drums); the latter replaced after their first gig by Martin Lamble.
 They were shortly thereafter joined by Judy Dyble (vocals), and Ian MacDonald (later known as Iain Matthews), joined them after they made their major London stage debut in one of Brian Epstein’s Sunday concerts at the Saville Theatre.
Iain Matthews (born Iain Matthew McDonald, 16 June 1946) is an English musician and songwriter.
 He was a singer with Fairport Convention before forming his own band, Matthews Southern Comfort, which had a UK number one in 1970 with a cover version of Joni Mitchell's song "Woodstock".
Liege & Lief is the fourth album by the English folk rock band Fairport Convention.
 It is the third and final album the group released in the UK in 1969, all of which prominently feature Sandy Denny as lead female vocalist (Denny did not appear on the group's 1968 debut album).
 It is also the very first Fairport album on which all songs have either been adapted (freely) from traditional British and Celtic folk material (for example "Matty Groves", "Tam Lin"), or else are original compositions (such as "Come All Ye", "Crazy Man Michael") written and performed in a similar style.
 By introducing songs of this genre into the group's repertoire Denny, who had previously sung and recorded traditional folk songs as a solo artist, was instrumental in this transformation.
 Although Denny quit the band even before the album's release, Fairport Convention has continued to the present day to make music almost exclusively within the traditional British folk music idiom, and are still most strongly associated with it.
Matthews' Southern Comfort is the debut solo album by country rock/folk rock musician Ian Matthews, and was his first album after leaving Fairport Convention in 1969.
 The musicians who played on it with Matthews were luminaries of the British folk rock scene and included ex-Fairport colleagues Ashley Hutchings, Simon Nicol and Richard Thompson, plus Gerry Conway, the drummer from Eclection and Fotheringay.
 The touring and recording band Matthews Southern Comfort who went on to release two more albums, "Second Spring" and "Later That Same Year", would not be formed till later, with only pedal steel player Gordon Huntley and Matthews appearing on all three albums.
 The album was released on the Uni label (a subsidiary of MCA Records) in January 1970 simultaneously with a first single "Colorado Springs Eternal", and took its name from a song, "Southern Comfort", by Canadian folk duo Ian and Sylvia (Tyson), which eventually appeared as the final track on "Second Spring".
