I think what you need is a big pile of hoops. Throw them on the ground and when they have finished rolling about some will land near and some will overlap.

Then the overlapping ones can be called things like A tune session and A singaroung, because they are not the same but they are a bit. Then you call another Morris Dancing and that might overlap a bit with another and that could be social dancing. Then that one by itself could be .... er ......... well you have a go.

I have got to go and see Fairport play Dylan in a knock out round at the Lowry. The winner goes through to meet Maddy Prior and her Festival Band in the semis traditionally played on Boxing Day.

I am glad I have been able to be of so much help. And don't forget my singaround at the Beech,

Cheers
