What is this word Freddie sings in "Under Pressure" -- Balop, Be lap, bay ...?

It is in the extended version – he seems to be just singing nonsensical rhyming sounds in this section, but I wondered if that word was real. I’ve seem it spelled “Be lap” in one set of lyrics.

Sir Rhosis

I think he’s just scatting.

Beezlebub bit the baby.

Beebop beats bang the bongo.

Bayside beans delay Bangor.
Or Alessan is correct. Whichever.

Exactly. Unlike, say, “Bohemian Rhapsody”, there aren’t any foreign words hidden in this song.

De de dep. Ba ba da bump bump. OK.
