I believe this is the second such event they've organised, and although I haven't been to this one I've gone to other events of theirs and I've known Colin Cater as a fine player of English music for donkey's years. It should be well worthwhile.
We have a day of workshops etc for melodeon and anglo players again this year on Saturday 19th March in Mendlesham, Suffolk. Classes for inexperienced anglo-players with Colin Cater and experienced with Andy Turner. Lots of other options to join with the melodeon players as well to work on waltzes, schottisches, tunes from Australia.
