From Michigan Rock and Roll Legends:
[Dick] Wagner next joined a popular Detroit-area club band called The Eldorados as their lead guitarist. The band had a sax player as well as a keyboardist named Warren Keith; and they played early Motown, Rock and Roll, and Blues covers. At one of the band's gigs, Mitch Ryder (then known as Billy Lee) was the guest vocalist. Wagner played with the group until they broke up in 1964.
