I've known Larry 'Bucketman' Hunt for a few years, he's a bit of a SF legend.
He can be found playing plastic buckets, paint cans, or his drum kit downtown just about any day.
He's so good at what he does that he's been invited to play in Germany and England.
On this occasion I could see a bus coming along that was going to make a good backdrop.
For the full story you can Google him.
