Procol Harum

One band isn't in even after being nominated 11 times.

Many of the genre's biggest names are still awaiting their induction.

With huge hits, multi-platinum albums and lasting legacies, these '60s artists certainly seem Hall-worthy.

He contributed to almost all of the band's song, including the classic hit "A Whiter Shade of Pale."

Musician played in progressive rock band from 1971 to 1976.
