Perhaps he 'lost is way'?
If you look at pictures of studios pre and post multi-track recording you'll see that with the with the advent of multi-track they started to cordon off some of the musicians, particularly the 'noisy' one e.g. the percussionists. Each had a way of signalling when they had 'lost their way' and so the entire recording would be wasted if they messed up). Listen to the guitar on Gene Pitney's 24 hours from Tulsa & around 2:40 (it wasn't Nile Rogers & the producer, wanted it left on the record)
True story.
I suppose the drummers went Cozy Powell?
However, in this case I suspect it's someone on mic when they shouldn't have been after a finishing their tea/coffee, in a Tommy Copper spoon-jar-jar stylee!
