Just listened to this on web-stream. After starting off with "Our Prayer" (sounds like VV to me), it has a lot of talking about what constitutes free jazz and blahblah (all in french), after which we get a five and a half minute performance of Truth Is Marching In. Sound Quality is pretty bad. The reason to keep this one is for the audience reaction, which is indeed wildly split between "cool beans!" and "WTF?!"
Apparantly, this is the missing piece from the 13 Nov. 1966 Salle Pleyel performance. I have never heard any of it, I'm afraid. For those interested, I have recorded the stream and have put the Truth online.
[drats! this whole lycos crap is driving me insane! ...hang on...]
sorry for the inconvenience, I've put the thing up under another directory/name. Please surf here: http://mitglied.lycos.de/couw/Ayler/
to find the mp3.
