Briggs, best known for his work with Neil Young and Spirit. Other musicians appearing on the album include George Harrison (credited as "George O'Hara"), Mick Taylor of the Rolling Stones, and Prairie Prince. Re-released by Columbia in 2004, the album features rare Hopkins vocal performances. His next solo album, entitled No More Changes, was released in 1975. Appearing on the album are Hopkins (lead vocals and all keyboards), David Tedstone (guitars), Michael Kennedy (guitars), Rick Wills (bass), and Eric Dillon (drums and percussion), with back-up vocals from Kathi McDonald, Lea Santo-Robertie, Doug Duffey and Dolly. A third album, Long Journey Home, has remained unreleased. He also released three soundtrack albums in Japan between 1992 and 1993, The Fugitive, Patio and Namiki Family. Other groups In 1967, he joined the Jeff Beck Group. Intended as a vehicle for former Yardbirds guitarist Jeff Beck, the band also included vocalist Rod Stewart, bassist Ronnie Wood and drummer Micky Waller. He remained with the ensemble through its dissolution in August 1969, performing on Truth (1968) and Beck-Ola (1969). He also began to record for several San Franciscan groups, including the New Riders of the Purple Sage, the Steve Miller Band and Jefferson Airplane, with whom he recorded the album Volunteers and also performed in the Woodstock Festival. From 1969 to 1970, Hopkins was a full member of Quicksilver Messenger Service, appearing on Shady Grove (1969), Just for Love (1970) and What About Me (1970). In 1975, he contributed to the Solid Silver reunion album as a session musician. By this point Hopkins was one of Britain's best-known session players, particularly through his work with the Rolling Stones and after playing electric piano on the Beatles' "Revolution". Further raising his profile, he contributed to several Harry Nilsson albums in the early 1970s, including Nilsson Schmilsson and Son of Schmilsson, and recordings by Donovan. In 1969, Hopkins was a member of the short-lived Sweet Thursday, a quintet comprising Hopkins, Alun Davies (who worked with Cat Stevens), Jon Mark, Harvey Burns and Brian Odgers. The band completed their eponymous debut album; however, the project was doomed from the start. Their American record label, Tetragrammaton Records, abruptly declared bankruptcy (by legend, the same day the album was released) with promotion and a possible tour never happening. In August 1975, he joined the Jerry Garcia Band, envisaged as a major creative vehicle for the guitarist during the mid-seventies hiatus
