Geo you hit it spot on. He is a rocker and it is hard to sing when you are used to loud guitars and such, most rock singers have to shout or really push to get above the drummers and other players. And you become used to that and its hard to sing somewhat quite, I know Ive been playin for over 25 yrs,but he is also getting up in age so his voice is starting to show the wear. If you wanna here him really sing, throw on "Sick as a Dog" or some early Aerosmith stuff, man the boy had some pipes back then.
