If you are good and you are also inventive, why not try playing some pop tunes in a traditional style. This is always a crowd pleaser and a neat trick, but not really that difficult. Richard Thompson does it with Oops I did it Again. People will find the tunes hauntingly familiar, but won't know that the reason is you are playing Brown Eyed Girl or I Want to Hold Your Hand.

In fact, many choir members can tell you that lots and lots of songs have the same number of syllables per line. Check out some of Burns' songs and see if you can easily fit them to some tune you already know. When I was cycling along the Speyside way, trying to memorize the Ode to a Haggis, I sang it aloud to Turkey in the Straw.

And no, it didn't quite fit, but I think I would have scared the pheasants anyway.
