When I was a little kid of three, four, and five, I didn't know the name of The Beatles' song "Love Me Do", let alone all of the lyrics (because until I had my tonsils out, I couldn't hear properly)... I could only identify it by the harmonica tune throughout, which, whenever I heard it, made me think of a farm scene (I don't know, there was something about the harmonica that made me think of a farm), so whenever I would TRY to talk about the song, I'd call it "The Barn Song"... and nobody knew what the Elmo I was talking about.
