Cam-Pact were formed in Melbourne in April 1967 with a line up of Mark Barnes on bass guitar (ex-Moppa Blues, Roadrunners, Delta Set); Keith Glass on vocals and guitar (Rising Sons, Eighteenth Century Quartet); John Pugh on guitar, vocals and autoharp (Roadrunners, Delta Set, Eighteenth Century Quartet); Chris Stockley on guitar (Roadrunners, Delta Set); and Bob Lloyd (aka Bob Tregilgus) on drums.
Although the group's membership changed frequently, the core performers of the Charles River Valley Boys in the early years were Eric Sackheim (guitar, mandolin), Bob Siggins (banjo, vocals), and Clay Jackson (guitar, vocals), all students at Harvard, and Ethan Signer (guitar, mandolin, autoharp, vocals), a graduate student at the Massachusetts Institute of Technology.
