On a CD called Romany Yog, produced by the Gordon Boswell Romany Museum in Lincolnshire, there is an interesting experiment with 3/2 rhythms. Tom Walsh plays the Old Lancaster Hornpipe on a melodeon while Amos Muller step-dances. Whether this bears any close relationship to what they did to the tune 200 years ago is anyone's guess, but it sounds fine( and fun) to me.
