It all goes back to definition of legend.
To me legend would mean someone/ band who have had a long and influential but not necessarily hugely successful in sales terms career.
To others it means an hour of songs they know but wouldnt necessarily want to pay to see.
Maybe its time to just let it die a,natural death rather than keep extending the meaning to make something fit as theyre avaialble.
Shania twain could still be playing but does it really need to be labelled legend.
