Best licks, IMHO:
"Gimme Shelter" - Stones
"Can't You Hear Me Knockin'" - Stones again
"Layla" - Derek and the Dominoes
"Won't Get Fooled Again" - Who, and my vote for all time best, most powerful Rock song, followed by "Behind Blue Eyes" from the same album (Who's Next)
That is an outstanding selection.
"In the Evening" by Led Zeppelin also has a nice intro
True story, I woke up on Election Day 2000, and CBS Radio news had a story about the last Dubya rally outside of Texas, in Little Rock of all places. They were playing "Don't Stop" by Fleetwood Mac, then all of a sudden, you hear this loud scratching sound as they drag the needle across a record. Next thing you know, they're cranking up "Won't Get Fooled Again". Funniest thing I ever heard.
