John Mayer & Eric Clapton - Crossroads

Here's a performance by Eric Clapton and John Mayer. They play the classic Johnson tune "Crossroads". The song was originally made under the title "Cross Road Blues" as a one-person acoustic blues tune by the ahead of his time talented Robert Johnson. The band Cream, of which Clapton was a member, covered the song on their "Wheels of Fire" album in an electrified version coming off the 60's blues vibe in London.
It is a blues classic, and Clapton's version has been covered by numerous artists, including Rush, Elmore James, John Mayer to name a few.

Enjoy ; )
