Frank Zappa the Mothers promo shot 1970

i was depressed so i bought myself something (I dont buy records anymore) this photo is from 1970 (i got it from a reliable source, but it was given out on the 70-71 tours) The guy with the big hair is Jeff Simmons, George Duke was on the 70 tour and came back in 73. That's Jim Pons from the Leaves/Turtles pointing. The film music guy Ian Underwood is in the foreground. he lives in lake oswego. This is the Fillmore East band, tho with a mediocre keyboardist that Don Preston replaced. (So it's half of the Turtles + George Duke + a Yale grad specializing in Mozart (ian) + that mustached guy)
