You could try 'My New Philosophy' from 'You're a Good Man, Charlie Brown'
'Food, Glorious Food' from 'Oliver.'
"When I Grow Up" from "Matilda the Musical". I'll look for the Junie B. Jones musical. My 11-year-old sixth grader devoured the books in kindergarten, first and second grades. (She read the kindergarten books in kindergarten, first grade in first grade and second grade in second grade. She went from first to second grade in one school year so it overlapped.) Matilda is one of her favorite books and was beside herself when my husband took her to the musical.
"The Ballad of the Putnam County Spelling Bee Blues".
