Done my fair share I think. First was at Covent Garden in 1975 and I've been to Nottingham, Gloucestershire, various GBBFs, Catford, Wandsworth and others over the years. Even helped to run a couple. Trouble is they tend to get a bit crammed these days so I try to look for an afternoon session where it might be quiet and I can get a sit down. Not getting any younger you know ....
