"Let a Frown Be Your Umbrella" is sung by Oscar and Farley, based on the 1927 hit, "Let a Smile Be Your Umbrella", written by Kahal, Wheeler and Fain (see box). As the song opens, Farley is singing the original lyrics, about how you can cheer yourself up on a rainy day by smiling. Oscar then sings his own lyrics about how he'd rather frown on a rainy day, because he likes to feel rotten.
- No songwriter credit is given for the new Grouch-related lyrics.
