one of the VERY few lead singers that has lost very little off of his voice would be Sammy Hagar. He can still belt out Montrose, Solo and Van Halen stuff, as well as everything from his post-Van Halen career. Honestly, I can't think of one single singer that has stood the test of time as well as he has (maybe McCartney, but Paul doesn't sing the wide-range of stuff or hard rock that Sammy does)
