Aerosmith started in the 70s, I think, and Steven Tyler still has it.

Start at the 5:25 mark to hear Steven Tyler hit those high notes. He's what? 66 or something there? Supposedly, your vocals weaken with age, but he still sounds amazing.
Another amazing vocalist is Miley Cyrus. She doesn't need to twerk. I don't get why she went that route when she's as talented as she is.
