Ray: Like to introduce the band: The Pachuco over there on '37 Chevy is Roy Estrada, on blankets Cherokee Jim Black, on rhythm guitar with a white light blue triangles behind him, Elliot Bro-Ingber, I'm Ray Collins, and this is Mother Superior Frank Zappa.

Bill Graham: One of the big advantages of having these people on the stage is that they're one of the few groups of this kind that you can listen to, turn on to, and then dance to. This evening we're gonna listen, if you want to, if during the first set you want to dance, use the corners or use the stage if you like. After Lenny we're gonna clear away most of these chairs and, do what you like. Everybody's relatives, The Mothers!
