Question:  For British markets Big Time was released as a double A-side single together with a song originally written and produced by who?
Context: "Big Time" is a song by Whigfield, and the single was released in July 1995, by X-Energy Records.  It peaked at #21 in the UK charts, giving her another big hit in that country.  For the British market Big Time was released as a double A-side single together with the song Last Christmas, a cover of the English duo Wham! . "Gamla Ullevi" / "Skisser för sommaren" is double A-side single by the Swedish alternative rock band Kent.  It was released on June 14, 2010 as the lead single from their ninth studio album, "En plats i solen".  It is their second double A-side single following "FF" / "VinterNoll2" from 2002.  Both tracks charted in the top of the Swedish chart, as number one and two respectively. "Kriss Kross" / "Clarion" is a double A-side single by multinational band Guillemots.  It was released on 28 September 2008 as a digital download, then as a limited edition 10" record two weeks later.  It was the first double A-side released by Guillemots.  Lead singer Fyfe Dangerfield explained: "We've always meant to put out a double A-side at some point, and we couldn't decide which of 'Kriss Kross' and 'Clarion' should be the next single, so now seemed like the right time to do both."  Dangerfield was the sole writer of "Clarion"; "Kriss Kross" was credited to the entire band.  Both songs were produced by Guillemots and record producer Adam Noble, and both were featured on Guillemots' second album, "Red". "Malaika" / "Consuela Biaz" is a double A-side single by German band Boney M. and the first single taken from their fifth album "Boonoonoonoos" (1981).  It peaked at #13 in the German charts, their lowest placing so far after their commercial breakthrough.  Boney M. would use the double A-side format in this period, typically with the A1 being the song intended for radio and A2 being more squarely aimed at discos.  "Consuela Biaz" was first promoted as the A-side in Germany where the group performed it in pop show Musikladen.  After a promotional visit to Spain where the group found "Malaika" had become a Top 10 hit, the title was remixed and then promoted as the A-side.  It was the second consecutive Boney M. single not to be released in the UK and Japan. "You Have Been Loved" (George Michael and David Austin) / "The Strangest Thing '97" (George Michael) is a double A-side single by British singer George Michael.  Both songs are from his 1996 album "Older".  The single reached number 2 on the UK charts, only behind Elton John's "Candle in the Wind 1997" charity single.  The song was Michael's second double A-side single, after "Older / I Can't Make You Love Me", released the same year. "Last Christmas" is a song by English pop duo Wham! , released on Epic Records in 1984, on a double A-side with "Everything She Wants".  Originally written and produced by George Michael, it has been covered by many artists since its original release. "Freaks" is a song by British neo-progressive rock band Marillion.  First released in 1985 on the B-side to the number five UK hit single "Lavender", in November 1988 it was released in a live version on a double A-side single together with the band's 1985 number two hit, "Kayleigh".  The single was intended to promote the forthcoming double-live album "The Thieving Magpie", which documents the band's history with singer Fish, who had left the band in October 1988; as such, this was Marillion's last ever single to feature Fish on vocals and cover art by Mark Wilkinson, who would go on to collaborate with Fish. "Bicycle Race" is a single by the British rock band Queen.  It was released on their 1978 album "Jazz" and written by Queen's frontman Freddie Mercury.  It was released as a double A-side single together with the song "Fat Bottomed Girls".

"Ismael" / "Varje gång du möter min blick" is double A-side single by Swedish alternative rock band Kent.  It was released on October 5, 2010 as the second single from their ninth studio album, "En plats i solen".  The single was released as a CD single limited to 1000 copies.  It is their third double A-side single following the album's lead single "Gamla Ullevi" / "Skisser för sommaren" and "FF" / "VinterNoll2" from "Vapen & ammunition". "Hourglass / Theme from Harry's Game" is a double A-side single by Irish musical group Clannad.  It was released in 1989 to promote their best-of "Past Present".  This is the band's only single to feature a lead song that doesn't appear on any album, and the band's only double A-side single to date.  Two promotional videos were produced to accompany the single, one for each of the lead songs, "Hourglass" directed by Tim Morris & Pól Brennan, and "Theme from Harry's Game" by Billy Magra.
