Scott Weiland of Stone Temple Pilots!! Also Nikki Six, Bono, and Zach De La Rocha of Rage Against The Machine (the dreads do it for me).
Hey shootingstar Eric Clapton totally hot young or old. Bob Seger reminds me of Toby Keith for some reason.
I found a slideshow of Sexy Rock Stars Over 40
Eddie Veder also hot especially if you're into the sexy Jesus look,
