I Made It Up.

The band’s manager picked the name.
He had a friend who had a cat called Procol Harum and
he thought it sounded good. The band didn’t know what it meant,
but later found out the Latin phrase procul harun means
“beyond these things,” which they thought appropriate.

Why the cat was named Procol Harum is not known.

And now a weird but special treat; the video below is no big deal by today’s standards but you’ve got to remember it was shot in freakin’ 1967, when there was no such thing as a consumer video camera. This is Procol Harum lip-synching their hit, A Whiter Shade of Pale, shot on 16mm film.
Dudes and Dudettes, this is a 45 year old HOME MOVIE. – Indy
