My only time at the Fillmore East and I was blown away! I remember Winter Consort had 1 song where it looked like blood was dripping down the screen and the singer was screaming in agony. These are the songs I remember Procol playing:
A Salty Dog
Devil Came From Kansas
Pilgrim's Progress
Shine On Brightly
Whisky Train
The Dead Man's Dream
Still There'll Be More
Nothing That I Didn't Know
About To Die
Barnyard Story
Piggy Pig Pig
Whaling Stories
Your Own Choice
Simple Sister
Power Failure
Good Golly Miss Molly

not in that order. There may have been more and there definitely was 2 more oldies in the encore. My understanding is Procol was not playing Whiter Shade at this time.
