It's been 40 years folks, still no thread? The song now has an official release on Spotify and all...
I was listening to the (alleged) 16 Feb 1981 performance on YT here.
Thought I'd note down a couple minor differences from the version we know from the Peel session and more recent live performances.
- after the 3rd chorus they go back to the first verse, followed by the chorus that ends with The Scream. Padding out the set I suppose.
- the "still I see hear see do talk see" line appears in the 2nd and additional 4th chorus instead of just the last one.
- "a green and pleasant land" instead of "a green sea, a pleasant land"
- "see the buildings crumble and the empires fall" instead of "see the buildings crumble, see the empires fall"
- "I count the changes and I count the cost" instead of "count the changes, count the cost"
- the 3rd chorus ends with a trailing "anymore" - as in "nothing but the good things ... anymore"
Also at the start Von seems to mumble "Oxygen" where he would be introducing the song, but I guess that might well be a comment on the situation in the venue rather an alternate name.
