A longer, different version later appears in "Stuck Together".
♪Oh! What a beautiful day!♪
♪It’s a day full of sunshine!♪
♪Oh, it's a beautiful day.♪
♪To make sure everyone has a beautiful day.♪
♪The sun is out.♪
♪And the flowers are too.♪
♪There's a smile for me and a smile-
- The "Stuck Together" version of this song bears a lyrical and melodic resemblance to the Beatles' song "Dear Prudence"
