Will Fly: I think it's easy to be too dogmatic with the use of the terms "singaround" and "session". On the one hand you have a circle of singers who take turns to sing a song, with or without accompaniment from the rest of the circle - and no tunes. On the other you have a gathering of instrumental players who all play together on sets of tunes - with no songs.
All very well, but in reality there are many, many different shadings - conventions, if you like - between the black of the one and the white of the other.
Absolutely, Will. The great thing about the Ditchling session is its variety. In a 30 minute window we can go from English, Scottish or Irish tunes through unaccompanied traditional song, through to Music Hall songs via jazz and folk revival and back to tunes again. By the strict definitions that "Guest" and others seem to want to apply it's a total mish-mash.
But it's lively, varied, interesting, welcoming to participants of every standard (though the general standard is very high)and a real joyous night out. By far the best "session" ( and I will call it a session!) I go (or indeed have ever gone) to. I travel an hour each way to it, and would happily travel 2 if necessary!
