When he was with the Floyd, towards the very end, Syd came in once and started playing this tune, and played it completely different. Every chord change just kept going somewhere else and he'd keep yelling (the title), 'Have you got it yet?' I guess then it was Roger (who kept yelling back, 'No!') who kind of realized, 'Oh, dear.'"
