Supergrass were an English rock band, formed in 1993 in Oxford. The band consisted of brothers Gaz (guitar and lead vocals) and Rob Coombes (keyboards and backing vocals), Mick Quinn (bass and backing vocals) and Danny Goffey (drums and backing vocals). Originally a 3-piece, Gaz's brother Rob Coombes officially joined the band in 2002. The band signed to Parlophone records in 1994 and produced I Should Coco (1995), the biggest selling debut album for the label since the Beatles' Please

At the age of 16 and 18 respectively, Gaz Coombes and Danny Goffey were members of shoegaze band The Jennifers along with Nick Goffey and Andy Davis. The band played gigs at various venues around Oxfordshire, often public houses and clubs. One pub the band played at was the Jericho Tavern in Oxford. The band enjoyed enough success to release one single in 1992, "Just Got Back Today", on Nude Records before they disbanded.  When Coombes began working at the local Harvester he befriended co-worker Mick Quinn. The two realised they had common music interests and Coombes invited Quinn to come and jam with himself and Goffey. In February 1993 they formed Theodore Supergrass, "for about two months" Quinn explains, "then we realized that Theodore was a bit rubbish so we took that off."  Goffey claims that the name was his idea and says; "Although the others will dispute it, it was me. We were Theodore Supergrass and the idea was the band would be a little black character, and we wouldn't ever have to do interviews. We'd get the questions in advance, script the answers and then animate Theodore Supergrass answering them. But it cost too much money."  Gaz's brother, Rob Coombes, played flute for the band's debut gig at the Co-Op Hall, Oxford in 1993. In January 1995 he first performed as keyboardist with the band for a live Radio 1 John Peel session. His role in the band progressed over the years, post-I Should Coco material is credited to "Supergrass and Rob Coombes", however, he wasn't introduced as a band member until almost a decade later.
