Tommy now that you mention it I think I have seen him perform in my travels in the Subway stations as I grew up in New York City & worked there for years....you would be surprised of the unbelievable talent underground people like the famous "Naked Cowboy" who is out there no matter what the weather in his underwear playing for the crowds in Times Square!
http://www.nakedcowboy.com/ and so many others. Many play at the 59th Street Columbus Ave Station due to that is the stop for LINCOLN CENTER for the Performing Arts & JULIARD School & a good place to be noticed by many Orchestra players from the Philharmonic, Opera, & Ballet..........many of these street players use battery powered Casio's KB's & portable Crate Taxi portable amps.
