Cats from Vanishing Point and rock legend

Yo if you have ever seen the movie "Vanishing Point" (a movie I admittedly became obsessed with for a bit after seeing at spencer's) then you will recognize the dude and chick singing as folks from the sick-ass snake handling church band Kowalski comes across in the desert. In addition to these folks you may also recognize the other cats on the stage as some of the dopest musicians of their generation, including but not limited too: Eric Clapton, Jim Gordon, Carl Radle, Bobby Whitlook, George Harrison, and apparently Billy Preston is in there somewhere too. sick.
