Is there a song you need to write?

Happy Birthday Johnny Cash, 1932.

Exercise 1: Have you ever written a poem that felt like it needed to be sung? Try and write a song lyric. It doesn’t have to be a complete song, just a phrase or two. See if you can set it to music. It can even be a familiar tune.
Exercise 2: Take a well-known lyric and change the words slightly, making them funny or different in some way.
