Just a random thought about Jagger and Richards. The best? I dunno, but I think Jagger was probably the most influential frontman in rock. Loved that blues-based roots of their rock. I think they kinda get overlooked by the Beatles, Led Zep I-IV, and even U2 live, but in terms of longevity I think they're still at the center of rock in general and all its various forms. Some of their covers were even better than the originals, but once they broke away from that is when they truly became great.
