Hi Frankie/Frankee,'twas me who mentioned the above. I have it on a Cropredy video from '82 or '83, and or an officially sanctioned 'bootleg' live recording from '82, and as far as I know does not appear on any other recordings.
If you want me to tape you a copy from the CD (for your own personal use of course),PM me. It's good fun!
