Authenticity, part V: Chicago Blues?

Some of you missed this in class yesterday: the great Muddy Waters at a Chicago club, being gracious enough to invite the Rolling Stones, visiting while on tour, up onstage with him.

More from the same evening: Waters invites bluesmen Buddy Guy and Lefty Dizz up onstage. Mick Jagger seems to silently acknowledge that he’s out of his depth.

As someone commented, Waters needed none of them, but they definitely needed him.
