In September 1966, Bentley left and was replaced by Bob Welsh on piano. The band released its first single, "Emergency Ward" (November 1966), backed by a cover version of Bo Diddley's "Who Do You Love?" as its B-side. Some sources cite "Emergency Ward" as a single by local DJ Ward Austin featuring Python Lee Jackson as his backing group. Their second single was a cover of Major Lance's "Um, Um, Um, Um, Um, Um", backed by "Big City Lights", in December 1966.
