The Unicorn saga began in 1963 when Ken Baker met Pat Martin at secondary school in England. They were both learning to play the guitar at the time, and soon began jamming on British beat tunes and Beatles covers in Martin's garage. Drummer and soon lead vocalist Peter Perrier was brought in and various people filled in on bass until Trevor Mee (who had been jamming with Tony Rivers & the Castaways) came aboard as a guitarist, with Martin switching over to bass. By 1968, they were playing gigs as the Late Edition (or simply the Late, as they called themselves by 1968) and backing other singers. In 1969, during a month-long residency in Copenhagen, they listened to the Crosby, Stills & Nash album, which been released in May of that year. It must have had a big impact, as the band returned to England and began transforming themselves into a country-rock outfit. They began working on new demos, which were eventually pitched to the Transatlantic label, who offered them a contract to record an album. A young producer and apprentice of Shel Talmy named Hugh Murphy was brought in to work with the group (he later produced Gerry Rafferty's "Baker Street" hit). The group tried out a few new monikers (including the Pink Bears) before deciding upon Unicorn for the release of their first single. A tribute to the American songwriter, "P.F. Sloan," their first single was released on Transatlantic's Big T label, which was known mostly for folk releases (Bert Jansch and John Renbourn). Their debut album, Uphill All the Way, was released on Big T in 1971. The next recordings were directly influenced by exposure to groups like Traffic. Around this same time, Mee left the group and was replaced by Kevin Smith (ex-Camel), who brought his love for the Clarence White-era Byrds into the group's repertoire. They toured around Europe, opening for the Flying Burrito Brothers on a television program in Holland. In 1973, Unicorn performed at the wedding reception of a friend, where they met another guest, David Gilmour of Pink Floyd, who joined them at the end of the evening during an impromptu jam of Neil Young's "Heart of Gold." Gilmour later offered to produce the band in a new studio he
