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. And those conventions are set by those who created the "sessionaround" in the first place. And, as long as all who attend are aware of the parameters and abide by them, everything works well.

It's music - remember? I've taken it very seriously for the greater part of my life- made money from it in fact - but not so seriously that I kowtow to rigid and arbitrary rules about how to make it for fun.
