From 1968 and German television, please enjoy Procol Harum's original classic lineup with the quite astonishing "Quite Rightly So."
This is by far the best video clip I've ever seen of the original 5-piece PH, and I'm gonna go out on a limb here and say they're actually playing live, given the differences between Gary Brooker's vocals and Robin Trower's guitar from the album track (although if memory serves, the single version was a little different, and perhaps they're lip-synching to that). In any case, this is exactly what PH sounded like in concert.
I've taken a fair amount of ribbing over the years in these precincts due to my enthusiasm for these guys, but I've said it before and I'll say it again -- I have never heard a more magnificent sound emanating from human beings on a stage than the one I encountered at various shows performed by Procol Harum (Mark 1) during their approximately three year run. I will further add that the group's seamless fusion of J.S. Bach and Ray Charles made them the only progressive rock band that ever mattered. So there.
Incidentally this was the first single from the group's sophomore LP (Shine on Brightly), as well as -- in its 45 incarnation -- the first music in stereo anybody heard by PH.
