A Day in Hollywood/Night in the Ukraine has only one, maybe two pianos. The way it's scored and arranged makes you feel like it's 10 musicians.
Occasionally a stray ukelele/gong/clarinet/harmonics is played onstage or briefly in the pit, but it's really just the piano.
I really hate all the orchestra downsizing crap and small pits in general, but I just love listening to this cast recording. It's great up on stage, too!
