I came across this smiling little rock on a fence along the bike path through Delta Ponds It reminded me of the song, perhaps you remember it. "Let a Smile Be Your Umbrella" is still a popular old song that was published in 1927. The music was written by Sammy Fain, the lyrics by Irving Kahal and Francis Wheeler. I don't believe I ever heard of them.
