the swingin' sixties

I'm taking things investigative, proving men (ok, rock stars) can be sexy at every decade (though for God's sake, I'm only going as young as the 20s).
Though, okay, I admit these guys were all better looking in the 70s, they ain't too bad today.
My Five Favorite Men Old Enough to Be My Grandfather (in no particular order):

Mick Jagger. Yes, he was a lot hotter in the 70s and 60s, but I think today he's looking better than the 80s and 90s...without looking Botox-infused.
Though I appreciate his decision to artificially keep his hair brown. I don't think he could work grey quite so well.
David Bowie.

Okay he's 59. But he turns 60 on January 8th...close enough! Jack Nicholson.
I love watching him act, I'll sit through stupid army movies (A Few Good Men) just to watch him. He's so naughty-seeming and sly, and unbelievably sexy. I, personally, cannot wait to see The Departed.
Bob Dylan. The only person on this list I've seen up close and personal (okay, from row M, seat 112), he's definitely looking good.

Keeeeeeith. I always find it funny that all the girls (at my school, at least) started lusting after Johnny Depp after Pirates of the Caribbean. They were in love with Jack Sparrow, a fictional person. Keith Richards is the true-to-life Captain Jack. (okay, Johnny Depp pulled it off well, and I was very into it, but Keith is still cooler)

Coming up: Are there any guys in their fifties that are hot? I can't think of any (besides Bowie) off the top of my head, but that's why it's called investigation.
