In hopes this is the same man. He is the rich uncle "Milton Pennybags" from the Monopoly board game. Marketed in 1935 to present from Parker Bros. The game was invented by Charles Darrow circa 1933. Maybe some of these names will help you. According to pictures , his vest,bowtie top hat and cane are the same as I have seen.
I cn't read music but I think those notes will help to decipher the quiz. Just guessing from the "trend line", Mr. Pennybags,etc. I would WAG the song is
"Were in the Money"
p.s. I got this from "The Monopoly Companion". One of many useless books in my own little library............
