How Do You Write Lyrics to a Melody?

Q: I have a melody and I want to put lyrics to it but I’m not sure how to do that. Is there a trick to this?

A: There are lots of ways to write songs. Some people write the melody or chords first, then add lyrics. Paul McCartney famously wrote the melody and chords to “Yesterday” before he had the lyrics. He went around singing the phrase “scrambled eggs” pr “ham and eggs” (depending on who’s telling the story) until he came up with the lyric “yesterday.”
