The original members, all from Union City were guitarist Ricky Zehringer (later known as Rick Derringer), his brother Randy on drums, and bassist Dennis Kelly. This first line-up was known as The Rick Z Combo, and later known as Rick and the Raiders. When Kelly left for college, the Zehringers were joined by bassist Randy Jo Hobbs, saxophonist Sean Michaels, and keyboardist Ronnie Brandon. This was the line-up that took the name of The McCoys. Brandon left the group in 1965 and was replaced by Bobby Peterson on keyboards.
