I don’t know much about Manilow’s politics, as he’s a very private person. But Andy Williams’ “Born Free” has always been one of my favorite songs, with lyrics that speak directly about personal liberty. I’ve spent time searching YouTube for various versions of it, as it’s been covered by many and one day stumbled upon a clip of Manilow speaking glowingly about it before singing it at one of his shows.

If those words are true to his heart, he may actually be on Rogan’s side on the issue. I found this about a recent Christmas concert of his, that did not require vaccinations, as well.

Maybe someone was playing a trick on him. Will be interesting if anything else comes of it.
