Question: The MGA Sessions is a solo album by Siobhan Fahey, more famous for Shakespear's Sister and which girl group?
Context: Siobhán Fahey ( , born 10 September 1958) is an Irish musician, whose vocal range is a light contralto.  She was a founding member of the 1980s British girl group Bananarama, who had a US number one hit with the 1986 single "Venus".  She later formed the Brit Award- and Ivor Novello Award-winning musical act Shakespears Sister, who had a UK number one hit with the 1992 single "Stay".  It was announced in April 2017 that Fahey would join the other original members of Bananarama for an upcoming UK tour. "Pulsatron" is a song by Siobhan Fahey, originally released in February 2005 from her debut solo album, which was later released as her project's fourth studio album "Songs from the Red Room".  The single peaked at #95 on the UK Singles Chart, marking Fahey and Shakespears Sister's last appearance on mainstream charts. The discography of UK-based pop-rock project Shakespears Sister consists of five studio albums, two compilation albums, 3 video albums, and 18 singles.  Originally a solo act consisting of ex-Bananarama member Siobhan Fahey, it eventually evolved into a duo between Fahey and Marcella Detroit.  They released their debut studio album "Sacred Heart" in 1989, which reached #9 on the UK Albums Chart and was certified gold by the BPI.  The album's lead single, double A Side "Break My Heart / Heroine" did not chart, the second single however, "You're History", reached #7 on the UK Singles Chart, and managed similar top 20 success internationally.  Their next three singles, "Run Silent", "Dirty Mind", and "Goodbye Cruel World" (the lead single from their second album "Hormonally Yours"), all failed to peak within the UK top 50.  The second single from "Hormonally Yours", "Stay" was the group's first and only #1, staying at the top position for 8 weeks.  The song also reached #1 in Ireland and Sweden, and peaked within the top 5 in several other territories.  "Hormonally Yours" peaked at #3 in the UK and was certified double platinum, and reached similar success in international territories. The MGA Sessions is the debut solo studio album by Irish singer-songwriter Siobhan Fahey.  The album was originally recorded in 1993, but was only released in 2005 exclusively through Fahey's website.  Since the revival of Fahey's project Shakespears Sister, this remains her only solo album to date. "Bad Blood" is a single originally released by Siobhan Fahey under her own name.  It was released in October 2005, and failed to chart.  Since its inclusion on Fahey's band Shakespears Sister's fourth studio album "Songs from the Red Room", it is considered a song by Shakespears Sister, and the third single from said album. "Cheers Then" is a song recorded by English girl group Bananarama.  It appears on their 1983 debut album "Deep Sea Skiving" and was released as its third single in November 1982, a few months before the album.  The song was the first Bananarama single to be written by group members Sara Dallin, Siobhan Fahey and Keren Woodward and also their first ballad release. Pop Life is the fifth studio album by British girl group Bananarama, released in 1991.  It is the only album released which features Jacquie O'Sullivan, who replaced Siobhan Fahey in Bananarama upon her departure in 1988.  This album marks the end of the group's association with the Stock Aitken Waterman production team (they produced only two songs) as most of "Pop Life" was produced by Youth (real name Martin Glover).  UK singer Zoë provided backing vocals on "Long Train Running".  This would be the last album by Bananarama as a trio. WOW!  is the fourth album by Bananarama, released in September 1987.  The album was entirely produced and co-written with the Stock Aitken Waterman production trio and is the last album by the girl group to generate significant chart hits in the US.  Tensions between group member Siobhan Fahey and Stock, Aitken and Waterman regarding songwriting input and lyrical content (particularly with the track "Strike it Rich" ) prompted Fahey's departure from Bananarama months after its release.  By the time the album's fourth single, "I Want You Back", was released, Fahey had been replaced with Jacquie O'Sullivan, who re-recorded the vocals for the single version of the song.  Fahey would resurface in 1988 with her new band, Shakespears Sister. Shakespears Sister is a pop-rock project, formed by Irish-born singer–songwriter Siobhan Fahey in 1988, and based in the United Kingdom.  Initially, Shakespears Sister was a solo act, but by 1989, it had become a duo with the addition of the American musician, Marcella Detroit.  Together they released two Top 10 albums and a string of Top 40 hits, including the 1992 hit "Stay" which peaked at No. 1 in the UK for eight consecutive weeks.  Detroit was fired from the band in 1993, leaving Fahey as the sole member again until she ended the project in 1996.  After working under her own name for some years, Fahey revived the Shakespears Sister name in 2009. Sacred Heart is the debut studio album by the British pop-rock project Shakespear's Sister, released on 21 August 1989 by FFRR Records.  The album was recorded after Siobhan Fahey decided to leave girl group Bananarama.  Initially intended as a solo act for Fahey, Shakespear's Sister became a partnership of Fahey and Marcella Detroit during the making of the album.  The album spawned four singles, including "You're History", released in July 1989, which reached No. 7 on the UK singles chart and was the first release to present the project as a duo.  The album peaked at No. 9 on the UK albums chart, and was certificated gold by the BPI.
