Which version is best?
Please make your decision on the merits of the performances only, and not the fact that Lennon/McCartney wrote the song. The song was written FOR the Stones, so it doesn't have that trademark "sweet" sound of the early Beatles. I prefer the Stones version! (gasp)
Of course, both versions are great, but one slightly edges out the other. Keith sounds like he is channeling Robert Johnson or somebody like that, but plugged in. AWESOME GUITAR NOISE!!!!
