Jason - in product development - was spotted with a guitar on his back on the elevator at a technology conference (the Symitar SymEast Users conference) and was asked why he wasn't invited to perform. He wasn't sure why, exactly; so this link was posted in order that visitors could listen and decide for themselves.
A couple guys, both called Dan, filmed Jason busking (playing in the streets); this recording is "Don't Let Me Down," one of his favorite Beatles songs to cover.
