I know there are some great sessions around in the UK (there's a great one on Sunday afternoons in Groningen in Holland which I went to a few weeks ago )but the point I was trying to make, is, that when I have visited festivals recently, they don't seem to cater for anyone wanting a musicians session. Plenty of singarounds / song gatherings , but I wish Organisers would make a fuss of the would-be musicians.
Even those of you who have a good local session it can become a little predictable as to which tune is following which, so, it's nice to get out with a bunch of relative strangers and not know which tune / and what key is coming next.
