Take Uptown Girl by Billy Joel.
Definitely has a Four Seasons vibe.
Did Billy Joel get sued for that?
Not that I’m aware of.
Inspiration isn’t the same thing as infringement, or is it?
Did Queen sue Vanilla Ice for Ice, Ice Baby?
Zep’s was not inspired by. It was outright theft!
Totally different. Jake Holmes wrote DaC, and LZ really ripped it off.
That was intentional, and some of the Four Seasons loved it. Tell Her About It was supposed to sound like early 60's girl groups. I think every song on that album was supposed to sound like his heroes.
