By mid-1965, Auger's band had grown to include guitarist Vic Briggs and vocalists Long John Baldry, Rod Stewart, and Julie Driscoll, and was renamed Steampacket. More a loosely organized musical revue than a group, Steampacket lasted a year before Stewart and Baldry left and the band split. Auger retained Driscoll and brought in bass player Dave Ambrose and drummer Clive Thacker to form a unit that was billed as Julie Driscoll, Brian Auger and the Trinity. Their first album, Open, was released in 1967 on Marmalade Records (owned by Auger's manager, Giorgio Gomelsky), but they didn't attract attention on record until the release of their single, "This Wheel's on Fire," (music and lyrics by Bob Dylan and Rick Danko) in the spring of 1968, which preceded the appearance of the song on the Band's Music from Big Pink album. The disc hit the top five in the U.K., after which Open belatedly reached the British charts. Auger and the Trinity recorded the instrumental album Definitely What! (1968) without Driscoll, then brought her back for the double-LP, Streetnoise (1968), which reached the U.S. charts on Atco Records shortly after a singles compilation, Jools & Brian, gave them their American debut on Capitol in 1969. Driscoll quit during a U.S. tour, but the Trinity stayed together long enough to record Befour (1970), which charted in the U.S. on RCA Records, before disbanding in July 1970.
