Lyrics
Richard: plish, splash, Elmo took a little bath Long about a Saturday night A'rub-a-dub, just relaxing in his tub Thinking everything was all right

Everyone: They was a'splishing and a'splashing There was a rolling and a'strolling There was a moving and a'grooving There was a reelin' and a'feelling Yeah! Put down the duckie if you wanna play the saxophone!
