On top of being a mysterious, pansexual rock god, Prince was also a very classy guy. Billboard recently talked to Journey songwriter Jonathan Cain and guitarist Neal Schon about a time in 1984 when Prince reached out to show them "Purple Rain," concerned that it sounded too similar to Journey's "Faithfully." Over the call, Prince said to Cain, "I want to play something for you, and I want you to check it out. The chord changes are close to 'Faithfully, and I don't want you to sue me." Cain heard him out and gave the go-ahead.
