The British band Procol Harum put out an LP in 1967 that featured the song A Whiter Shade of Pale. As a young man I was listening to an FM radio station one night when this song came on and the DJ explained that this was the song that made rock gentle. Oh yeah.
And the fact that the album also contained the song Conquistador made it one of the great albums, in my top ten, of all time.
Conquistador, there is no time, I must pay my respects
And though I came to jeer at you, I leave now with regrets
And as the gloom begins to fall
I see there is no, only all
And though you came with sword held high
You did not conquer, only die
The truth is plain to see. Procol Harum, A Whiter Shade of Pale.
