I've been listening to this fine recording of Adele singing Rolling in the Deep. It looks like it was done in a recording studio. At the beginning and at the very end the sound engineer says a few words. What he says at the beginning is fairly clear, but no matter how many times I have played it I cannot make out what he says at the end. I don't know whether it is an accent, slang, jargon, a foreign language or speaking in tongues. It's just the weirdest thing.
