Ah! Dave Betteridge - I'm pretty sure that was him, because as I said, I did see him doing solo gigs, as well as appear with the duo, so his name would have been announced. So it must have been the Dixie Ramblers. I wasn't sure before, but I'm pretty sure you're right. Does anyone know what happened to them?

Thanks to all who have provided info, and apologies for hijacking the thread Tim!
