Flutist Doug Tessler was so nervous about what his dentist, Dr. Steve Rosenberg, was going to find when he went for a check, that all he could think of was to start playing to the music on the radio. Steve Rosenberg, Doug's friend, heard him playing, grabbed his guitar and just figured out a way to sit in the hygenist's chair and started playing along to the song on the radio, 'For What It's Worth.'
