Question: Simon Ellis has produced songs for which English pop group formed in 1994? 
Context: Searching for the Young Soul Rebels is the debut studio album by English pop group Dexys Midnight Runners, released on 11 July 1980, through EMI Records.  Led by Kevin Rowland, the group formed in 1978 in Birmingham, England, and formed a strong live reputation before recording their first material.  Recorded during April 1980, the album combines the aggressiveness of punk rock with soul music, particularly influenced by the Northern soul movement. The Blue Ox Babes were an English pop group, formed in early 1981 by the former Dexys Midnight Runners guitarist Kevin 'Al' Archer, together with his girlfriend Yasmin Saleh, guitarist Nick Bache and former Dexys keyboard player Andy Leek.  Archer was keen to mix the soul sounds of his previous group with folk styles.  To this end he recruited fiddle player Helen O'Hara to play on demo tapes of the new songs he had written.  When former colleague Kevin Rowland heard these demo tapes, he invited O'Hara to join Dexys, and adopted a similarly folk-influenced sound for his own group. 7 is the second studio album by British pop group S Club 7.
