Found this video on You Tube from the Cliff Richard channel ,this must be the earliest video of Cliff and The Drifters as they were then.But the strangest thing is you can only see Jet Harris ,and Terry Smart who is only playing one drum ,Jet is playing his Framus bass, but there is no sign of Hank or Bruce they joined the group before Jet did .On the tape you can hear a piano playing and vocal backing , the Oh Boy shows were live no miming so perhaps members of the resident band were playing also the vocals could have been done by the Dallas Boys.This must be the only video to feature Terry Smart.
