Tunesmith, you are right. But Bert was all there was at the time - well, Bert and Lonnie Donegan. Myself and three pals entered a skiffle competition in a local church hall, we were all eleven years old and Bert Weedon was judging. We played I Shall Not Be Moved and Mama don't Allow. We must have been awful but Bert wrote on the bottom of our "report" sheet - "Good effort for such youngsters". Trouble is, I never got any better!
