Six of their nine singles made regional Top 40s throughout Michigan, Ohio and New York, with two of them – "You're a Better Man Than I" (originally by The Yardbirds) and "I (Who Have Nothing)" (a cover of a Ben E. King song) – reaching the national charts. "I (Who Have Nothing)" went to No. 46 and earned the band an appearance on Dick Clark's television program "Where the Action Is". In the summer of 1966, Farner leaves the band to go join Dick Wagner’s band, The Bossmen, allowing Jackson to return to the group. Their debut album, "Terry Knight and the Pack", was released in 1966.
