yeah cause dave is a kick ass guitar player and in nick masons prime he was a kick ass drummer i think he the only one ever to tour with tympanis. but yeah all i saw was nick and roger there stuff really dominated the movie but we did get to dave's saucer solo and some other solo work BEHIND ROGER.... cause he always does great guitar work he could even make the mad scientist sound work and also sublimital guitar sounds
another thing i love about that movie was the camera work on echos i like the part in the funky section of the song were the camera on the track is rolling by looking at them wile the cabnets are in the way i just think that seems so odd its cool

i just love the sound they were able to get out on the day of recording cause it takes alot of work to set up your effects to get the right sound
but that might lead into the overdubbing people say they did on the concert
