Thing is, John, some of those thumpers and scrapers (well, maybe not thumpers - I got chucked off that ITM graveyard Fish and Chipple 14 years ago for dissing a thumper...) are actually exceptionally good musicians. Had you said thumpers and strummers I might have been closer to concurring... There are good and bad in every genre. Bad strummers, bad scrapers, bad thumpers (there are only BAD thumpers in m'humble). I wouldn't go to sessions in which there was a perceivable undercurrent of prejudice against any element (except for thumpers). There's room for all sorts, but no room for either song-takeover merchants or tune-takeover merchants. If you're (a) really terrible, or (b) full of ego, then you may be told to bugger off. Let's have fun. Unless you're making money, there's nothing else for it.
