The Fugs actually recorded a version of "Howl". Not the whole poem, of course. A bit of a shouty / punky / explosive tune:
"I saw
The best minds
Of my generation
Destroyedbymadness....." etc etc

Fabulous.

There is also an album by Mudboy & The Neutrons called "Negro Streets At Dawn".

I think the words you quoted are from Ginsberg.
