John Wintermute told his co-worker Alex Dean that he was planning to make a song about legalizing marijuana. Alex thought a song about legalizing marijuana would be a great way to book some new gigs, so he talked to his bandmates, Alexia Rose and Michelle Martinez, about writing a song about legalizing marijuana. The trio wrote the lyrics and the music to the song in one day, and recorded a demo and sent it out to record labels. A few months later John hears the song on the radio and feels betrayed by Alex. He sues Alex for copyright infringement.One of the matters before the court is whether John had a protectable copyright interest. Does he? Please explain your answer.
