Roy Orbison was an influential American singer-songwriter and rock-and-roll pioneer whose career spanned more than three decades. He had a string of hits during the early-1960s, such as “Only the Lonely” and “Oh, Pretty Woman,” after which his career waned, driven in part by a series of personal tragedies. He made a comeback in the 1980s, forming a supergroup with Bob Dylan, George Harrison, and Tom Petty called the Traveling Wilburys. What was Orbison rarely seen in public without? Discuss
