Ah yes, the 'fox hat' joke.

Props needed:

1. Audience (and performer) with juvenile sense of humour,

2. A gig somewhere off the beaten track,

3. A hat either clearly made from, or depicting, a fox. I found a nice cartoony picture on Google Images, and stapled it to an old straw hat.

Ready? Don the hat, at the same time remarking, 'When I told my friends I was going to play at (wherever), they said, 'Wear the fox hat!' (Cue helpless laughter, free beer, groupies, etc).

Perhaps you'd have to be there....

I'll get me coat.

Oh, and it was a great evening. Doc at his best.
