Stones, guys, Stones! After thirty years, I can't get these out of my head:

Into to "Jumpin Jack Flash" (especially from Ya Ya) Intro to "Under My Thumb" Intro and repeat in "Satisfaction"

Additionally, the Who covered "Young Man's Blues" on their Live at Leeds album. Listen to that introductory lick.

Oh yeah, and how 'bout the intro to Sweet Jane on Lou Reed's "Rock N Roll Animal"

Hard to stop....
