I'm assuming the Sunday lunchtime 'acts' at Rawmarsh C.C. don't count?
I couldn't say if I had any favourites because I don't think I saw that many and certainly didn't see any one of them more than once. Actually I tell a lie, The Roger Brooks band played at the C.C. every Friday night but they weren't really an 'act' as it was a weekly event "Dancing with....".
3 acts I do remember seeing/enjoying from Rawmarsh clubs were Roy and the Mighty Atom, David Copperfield and Ray (Roy?) Belcher, a comedian and the postman from the Hovis advert.
