Topic: Can I reference a real song and artist in a work of fiction?
I'm in the middle of planning a Christian trilogy, and I would like a devout Catholic teenager to listen to Battle Hymn of the Republic by Lee Greenwood. What are the rules in a case like that? Do I need the artist's permission? The song is in the public domain. My reason for wanting to name this particular singer is to promote his version of the song. He sings the historical Civil War lyrics, not the modern version.
Thanks.
Dirk
