Struggling to think of any other 60-year-old artists who would have three top ten hits at that age.
He did extremely well with Quarry aged 45. Four UK top ten singles and #2 on the albums chart. Can't think of any other singers who did that at that age.
At Morrissey's stage of life he simply isn't going to get that type of success again. He could reunite with Marr and put out on album deemed even better than The Queen Is Dead and he wouldn't enjoy that level of chart success.
