For debate sake....... im going to have to go with Mick Jagger, hes performed at a high level for over 40 years now. No one else has done what hes done with the same band. Steven Tyler has a chance but you never know.<P>To me theres really more of a group of great front men than an actual best. Id go with Plant, Diamond Dave, Freddy Mercury, Steven Tyler, Mick jagger, Vince Neil, Scott Weiland, Axl, Roger Daultry. Theres many more who are good, but these are definately some of the best.
