Dr Zoom & The Sonic Boom was a very short lived progression of Springsteen’s March 1971 'Friendly Enemies' shows at Sunshine In and his April 1971 'Jam Concerts' at The Upstage. The members of Dr Zoom were Springsteen, Steve Van Zandt, David Sancious, Garry Tallent, Vini Lopez, Southside Johnny plus Bobby Williams (percussion), Albee 'Albany Al' Tellone (sax, vocals) and Bobby Feigenbaum (sax). There was also a 7 member backing vocal troupe nicknamed 'The Zoomettes' (Jeannie Clark, Robin Nash, Connie, Kevin Kavanaugh plus 3 others). The MC was Kevin Connair. Danny Gallagher handled the on-stage props. They played just two concerts in May 1971.
