From the 'Down Beat' 1975 poll-winners' show, a performance of Rahsaan Roland Kirk's 'Pedal Up'.
Rahsaan Roland Kirk - horns
McCoy Tyner - piano
Stanley Clarke - bass
Lenny White - drums
The performance is introduced by Quincy Jones.
This performance (and the whole poll-winners' show) was produced by WTTW Chicacgo and distributed by PBS I believe. To the best of my research, this footage has never been commerically available to the general public in any home format. It's been circulating in bootleg trading circles for some years, where I obtained it. I'm sure many of us would love to have a proper DVD of these Soundstage shows! I will happily remove it at the request of the musicians or the copyright holders.
