Apparently, Dio didn't want to include "Rainbow in the Dark" on the album Holy Diver. He thought it sounded too "poppy". He literally wanted the song destroyed so no one could hear it.
Got to be honest, he's not wrong. About the "pop" thing. It's the keyboards. Hard to not be "pop" when using keyboards.
Then again, it was the 80's. Keyboards were in the air.
Van Halen's "Jump" came out a year after Holy Diver. Of course, "Jump" had a lot to do with David Lee Roth leaving Van Halen, but this isn't about Roth, is it?
And 4 years later Iron Maiden used keyboards to great affect on their Seventh Son of a Seventh Son album and that album's not too pop. I guess.
Some people got together and remade the video to Rainbow in the Dark.
Some people have too much time on their hands.
