Well, Geoff has been with Radio Merseyside almost since it first opened. It could have been Stan Ambrose of course, but I think Geoff would still know. The early fifties would have been during the BBC's folk music collecting programme and I think it's far more likely to have been one of the collectors who was working for them. But if so I'd expect the recording to have shown up on the NSA database.

Anybody else capable of throwing some light on this?
