The London School Of Economics theatre wasn't the ideal place. Curious beer swilling students wandering in and out. I wasn't well seated but the music, and especially Ayler's sound was terrific. Beaver Harris too was something else. The format was two sets to be video'd for televising on the BBC. "The Truth Is Marching In" was the only piece played, repeated in both sets (about 40 minutes each as I recall, the set time being dictated by the programme length).
The video was wiped by the BBC allegedly because the Controller thought it to awful to broadcast-or maybe it was Beaver Harris in a vest which caused the problem.
