Bob Relf was never in the group.
At the time of the Keymen 45 they were Jimmy Locke, Alvin Sykes, Walter Pride, James C Brown and a guy named Gene-I've not found his surname. Jimmy Locke is the most featured so may have been the lead.
Nobody But You Girl
The Preparations
I could do with hearing either of these, also Wasted Days by Sebastian on Brown Dog.
Ta
Ady
Nothing Between Us
Electric Ladies
PS I like Wait and it sounds black to me. Bobby Dunn seems to have been a gospel writer mainly. In 1963 the soul sound wasn't so accentuated on records.
