Les, you are giving morris dancers credit for a lot more organization than is possible! Who decides what the next dance will be? Who knows?
The Harrisville (NH) morris women have one song that inspired the dance one of our members wrote years ago, "Durham Jail"
We always start by singing,

Oh, never in the livelong day,
You'll not find me back in Durham Jail
Oh, never in the livelong day,
You'll not find me back in Durham Jail"

It's a fun dance. The song always gets my adrenalin going!
