More Furious Madness From the Massed Gadgets of Auximenes 

This is about 20 mins of b/w footage shot at the Royal Festival Hall by Anthony Stern (it sez so right there on the opening slate). It seems that Stern was called earlier that day by the band to shoot this amazing and unique performance. Unfortunately, he didn't go through all the proper channels, and only got permission from the RFH to shoot the rehearsals and only in certain areas of the venue. This becomes apparent when the venue's security "busts" him and orders him tu turn over all his equipment. This all takes place while the camera is still rolling, but with audio only! You can hear the escalating dialogue between Anthony and security (management as he pleads his case). Too bad he didn't go through the proper channels and pay for the rights to film the actual show, as he was evidently prepared to do, but at least we have this incredible rehearsal footage to marvel at. That's the story I heard and this is how I pieced this thing together. Maybe a phone call to Mr. Stern would clear thing up. There is also current speculation that the actual performance was filmed as well (quoted recently by Roger Waters).
Songs include Biding My Time (with Rick briefly on trombone), Green Is The Color, Cymbaline, and A Saucerful Of Secrets, all incomplete but still wonderful to watch!
