9. The Who
No sane rock fan can dispute that the Who are one of the greatest bands of all time. Live music simply does not get better than their concerts in the 1960s and early 1970s, and their run of albums from 1965 to 1975 is simply staggering. Each one is radically different from the previous one, though no less brilliant.
That said, even before Keith Moon died in 1978, they were a band in decline. They bounced back in a huge way in 1999 when they stripped back to a five-man lineup, but just three years later, bassist John Entwistle died. It was a devastating blow. The band is literally half-dead now.
Roger Daltrey's vocal problems aren't as bad as they were a few years ago, and their recent Quadrophenia tour was impressive, but it's far from crazy to suggest they think about hanging it up. The group agrees and are planning their "last big tour" in 2015.
"We have to be realistic about our age," Daltrey said last year. "The touring is incredibly grinding on the body and we have to draw a line in the sand somewhere."
