It went something like this....

Hugh's organ and Guy's drums heard in tune-up mode.
"La Rossa", announces PH.
The band begins to play and you can here the organ, but PH so faint you can hardly hear him.
Shouts of "start again Peter" heard from audience. Band stops playing.

DJ, John Peel, heard on PA, "One...Sorry about a certain amount of confusion. There seems to be some water in the amplification equipment. You've probably noticed that it's been raining a little bit - a light drizzle in the last hour or two. As soon as we can get that sorted out we'll be back again with the lads. Don't panic it'll be alright".

Sometime later....
Peter Hammill on stage; "Well, well, well".
"We're gonna do something different now. We're not going to do La Rossa after all because that delay has killed it. It's going to be a new song which is called "Masks".

Band plays "Masks" (to be on World Record)

PH; "Thankyou, The next two songs are from the album Still Life and the first of them is called Childlike Faith in Childhood's End".

Band plays "Childlike Faith in Childhood's End"

PH; "If you like quiet songs of deep intensity, we are about to do a very quiet song. This is called Still Life".

Band plays "Still Life"

PH; "Thankyou very much, This is from Godbluff and it's called The Sleepwalkers".

Band plays "Sleepwalkers"

PH; "....Unprecedented since we reformed, almost certainly the only time, and that's to make up for the rain, we are now going to play Killer".

Band plays "Killer"

PH; "Goodbye, see you again I hope".

JP; "Bloody marvellous, Van der Graaf Generator. Come on let's here it for them".
