Thanks for the comments guys!
Gepetto - yes, wedge = folding money.

I have never "performed" at the Oxford Folk Festival, though I have played along in music sessions there a few times. Our Morris team are based in Kingston-on-Thames, about 2 hours away by train, so I don't think we'd ever perform here as a team, but I enjoy seeing the other teams, recognising the dances and tunes, and stealing ideas.
Our Morris team starts the season next week "dancing out" in the New Forest, and then we have something most weeks till mid-June when I'm off to Ireland for a fortnight's holiday.
