"shave and a haircut, two bits"

I don't know what a bit is, but I've got a tape of him at the Seville Guitar Legends Festival performing with a load of guitar wizards.

He makes the best entrance ever and milks the crowd for all its worth, he said in an interview that he opened the door with THAT beat, and everyone rushed through while he was still holding the handle...

I wonder who made those weird shaped Cigar box guitars for him?
