Guys and Dolls/Heartwarming

• "More I Cannot Wish You"
• "My Time Of Day/I've Never Been In Love Before" also qualifies.
• Meta-example: Nathan Lane was born with the name Joseph Lane, but had to change it when he became an actor because another actor already had that name. He chose the first name "Nathan" because he had always wanted to play Nathan Detroit. In 1992, he got his chance (and a Tony Award nomination) when the musical was revived on Broadway.
