Now let me tell you a story I got from a friend who's a rock journo. He interviewed one of TOPower guys, who talked about the Frisco'81 shows which they opened for.
An agreement had been made between the 2 bands : TOP would join the Stones a add their brass sound to the final song.
After JJF the Stones leave the stage to a little rest backstage. After 1 or 2 minutes a Stones stagehand calls TOP for Satisfaction.
The Stones come back... except Keith's missing. Panic! Everyone paces the large backstage area to find the guitarist... and someone discovers him passed out, lying on the floor, in a "Jesus Chrsit pose", stoned from taking too much of the "stuff" in too little time.
Soemehow Keith was revived and went on stage to play "Satisfcation" with Tower Of Power
I'll DL this tape asap. Thx Jos!
