I know EXACTLY what you mean.Sometimes,I actually become a little sad when I hear how worn Paul's voicebox has become over the years.Just recently it occurred to me just how much screaming he's done("Twist and Shout","Long Tall Sally,etc.)and it amazes me that he can still pull off a concert half decently.What saddens me even more is you don't even see Ringo play drums much if at all anymore.I do realize that there are moments of thinking "well,he's not what he USED to be",but then again,who the hell is by 70.
