Here's one that's amazing...an older gentleman playing the fiddle with one arm, bow held between his thighs AND it's his right hand he's fingering the notes with! According to one comment he's playing the Rosebud of Avenmore, though I couldn't swear to it, not being familiar with that tune. If you watch to the very end, there's a good close up which shows his technique.
