Friday sessions are mostly tunes rather than a singaround but singers are encouraged to do things too. There are long bits of the evening when there is just playing so someone expecting a lot of songs could get fed up in those bits, but it is a mixed session. It doesn't go round in a circle but in case anyone feels left out someone regularly asks 'is there anyone waiting to do something that hasn't been able to get their tune or song in?'
If it's too busy on the Friday of the festival for everyone to do what they want there can be several sessions in different rooms all at the same time. Its a solid old pub and the walls are thick.
