4. Casey James. Yes, Casey did Huey Lewis and the News' "The Power of Love" and no, it wasn't all that bad. Hey, at least he wasn't mugging on a stool or hiding behind his guitar (even if he did riff out). It was still a vocal performance, and he did his best to come alive (a problem he's been having). Simon said the performance was old fashioned (he called the original old fashioned, too, whatever that means) and he was only partially right. The chorus had a timeless swing to it that seems to endure, no matter the decade. Kudos to Casey for showing he's more than long hair, but still, out of all the Billboard No. 1's, you go with Huey Lewis and the News?
