of course hitting high notes doesn't mean singing better. i agree with you.
but if one CAN'T hit those notes (which is perfectly natural for an almost-50 year old who has been smoking for the past 15) then why not lowering the key of certain songs even further ? people say they might sound flat but they never heard always, dry county and these days a full town lower, instead of just a half tone. i know this discussion has been going on for ages now, but the only reason I'm complaining it because people pay a lot of money to see that band !
