Eric Clapton has recruited a clutch of his guitar great pals to perform at his second Crossroads Guitar Festival this summer (07). B.B. KING, Robert Cray, ALBERT LEE, John Mayer and Jeff Beck will join Sheryl Crow and country stars Vince Gill and Willie Nelson at the benefit show in Chicago, Illinois. Clapton's first Crossroads event, staged to raise cash for his Antigua-based rehab clinic, was held in Dallas, Texas in 2004.
