Universally hailed as the reigning king of the blues, due to popular demand, B.B. King comes out of retirement and returns to the UK and will embark on four arena concerts in June 2009.

The blues guitar icon will team up with the legendary British blues virtuoso John Mayall to share the once in a lifetime double bill for what is set to be one of the most spectacular rhythm'n'blues concert tours ever to hit the UK in years.
