Close to morning, I found myself either leading or watching a small rock group in a studio, rehearsing a new song, presumably to record it when the arrangement was set. Lucky us, we had John Lennon and Paul McCartney there to help with back-up vocals. Set to come in on the second verse, McCartney came up with a back-up answering vocal for the lead, under which he and John would keep singing "Baby, can you run?" Lennon changed it so it would go "Baby, can you run? Baby, can you run now?" (He messed it up and came in wrong initially, but they immediately realized this was an improvement.)
I know the notes, but would need a piano to identify them. I don't remember the lead melody, if indeed there was one. And again it was fluid whether I was watching or participating. But anyway then the alarm went off.
Certainly better than dreaming about current U.S. politics.
