The Traveling Wilburys was a fortunate accident that George Harrison concocted to fill the B-side of a single for “This Is Love,” from his Cloud Nine album. It was customary to add a never-before heard track to the flip side of a single. George just happened to be hanging out in with Jeff Lynne and their friends Bob Dylan, Tom Petty, and Roy Orbison, at Dylan’s studio when it dawned on him to record a jam session for his B-side. They nailed it. The concept of a full scale collaborative album was the natural next step.
