I was fortunate enough to have been able to catch the AB's at the Fillmore East during the engagement that produced the legendary live records. Imagine, the Elvin Bishop Band (he had the Pointer Sisters singing back-up!) 3rd billing, Johnny Winter And 2nd billing, and the Allmans top billing! S'funny, the original billing had the AB's 2nd to Winter, but I distinctly recall the Allmans coming on last. Didn't happen during my set but I read during the late show's that Elvin, Johnny, & Rick joined Duane & Dickie for a late night jam. Man, sometimes the music at the Fillmore just seemed to levitate! The best of times!!!;)
