Carol C,

You can have great fun with an accordion. The lead musician with our morris side has been playing for country dances for 40 years, and is pretty damn good. If he's in a session and someone needs taking down a peg he just does some really well-known tune, but in Eb or B or some other key the pissy D/G box-players can't handle. Their faces are a treat when they realise what's happening.
