This may seem like a dopy question, but can anyone tell me (with examples), how the Doo-Wop groups (and/or the Girl Groups) did their stuff technically? I have vaguely assumed that sometimes people sang in thirds around each other, and did barber shop things. But I have never seen or read a musical analysis of the sounds these guys and girls got up to -- innovations, etc. Anyone ever been in one of these groups and can give some inside info.?

yours,

Peter T.
