From January to July 1966, EC played club dates with John Mayall. Clapton's scorching club performances in London during this time quickly established a cult following for the young guitarrist. "Clapton Is God" graffiti began appearing around the city, defining a central tenet of Clapton mythology to this day.
John regularly taped the gigs with his 2-track reel-to-reel, bad sadly these tapes were detroyed in a fire in 1979 at his Laurel Canyon home, only 30 minutes of a show in the Flamingo survived and were later released as an official John Mayall album.
