“HANDLE WITH CARE”
The birth of the Travelling Wilburys was a happy accident. Warner Bros. Records' International Department had asked that George Harrison come up with a B-side for "This Is Love," a single from his Cloud Nine album. At the time it was customary to couple an A-side with a never-before-heard track, giving the single extra sales value.

This was mid-1988. Cloud Nine was just out. George, along with co-writer Jeff Lynne and their friends Bob Dylan, Tom Petty, and Roy Orbison, had been hanging out in Dylan's studio. I suppose George figured that as long as his pals were on hand, why not use them to knock off this flipside?

Upon hearing the music collaboration, the record company immediately released the song as on its own, and the birth of a new supergroup became a reality.

"WHILE MY GUITAR GENTLY WEEPS" is a song written by George Harrison of The Beatles for their double album The Beatles (also known as The White Album). The song was ranked #135 on Rolling Stone's list of the 500 greatest songs of all time and #7 on their list of the 100 greatest guitar songs of all time.
The band recorded the song several times, including a version with a backward guitar solo but Harrison was not satisfied. On 6 September 1968, during a ride from Surrey into London, Harrison asked Eric Clapton to add a lead guitar solo to the song. Clapton was reluctant—he said, "Nobody ever plays on the Beatles' records"—but Harrison convinced him and Clapton's solo was recorded that evening. Harrison later said that in addition to his solo, Clapton's presence had another effect on the band: "It made them all try a bit harder; they were all on their best behaviour."
