We go to a small tunes/ songs session. Last time the person usually loosely in charge was not there and we went 'round the room'.
This was a mistake as the people sat near each other did similar things, e.g. 6 lots of dance tunes / 3 not-quite-folk-songs, etc.
It would have worked better if we'd mixed it up - 1 from this table, 9ne from another.
