Digeridoo?

I actually heard the didgeridoo today in the 16th/Mission BART Station today. Pretty surreal, I only saw a glimpse and didn't want to take a photo (for fear of getting charged, like the shoe shiners on Stockton and Market), so all I have as proof of the man, sitting on the floor, with a loooong bright yellow didgeridoo out in front of him. I need to get batteries for my camera, I haven't taken enough pictures lately...
