Guitarist and singer/songwriter Bob Segarini formed the Wackers in 1970 in Montreal, Canada. The artists he pulled together for this new group were guitarist, keyboardist, and bassist Randy Bishop; pianist and guitarist Michael Stull; bassist and guitarist Bill Trochim; and drummer Spencer Earnshaw. After three years, the lineup lost Stull, and drummer Gerry Mercer was brought in to help out. All of the members came into the act with plenty of experience. After recording four albums, the group called it quits in 1974.
