We haven't been to Towersey but did go to Bridgnorth three years ago. We don't go to Concerts but the campsite was very nice, very big and with a more kind of cool atmosphere than most folky campsites (veggy food tent, circus performers, woman with a strange type of bus wagon thingy for kids). It is a nice walk down to the town; i remember we went down on the Friday night and didn't find any music but had a very civilised evening around the pubs amongst pleasant company. On the Saturday I seem to remember there was something going on in the Railway Station Bar...and we sat in the back garden of a pub and had a good afternoon in the sun with a good singaround type thingy. Unless it has changed alot though, or there is stuff going on at the school site, the singaround side of things was very low key and I wouldn't bank on finding loads of sessions around the town. Heck why not save all the heartache and worry and get yourself up to Whitby where you won't fail but have a good time!
