As a kid, my family watched the Donny and Marie show every week. He's still one of my favorite perfomers. My wife and I showed our kids the movie version of Joseph's Technicolor Dreamcoat with him in the lead role. And we also knew from week 1 that he was the Peacock on the Masked Singer.
So, a bit of a fan and have been dying to work that reference in somehow.
It was easier than trying for the Side By Side bit.
