Question: what was roy orbison's first number one hit
Answer: Back in the studio , seeking a change from the pop sound of `` Only the Lonely '' and `` I 'm Hurtin ' '' , Orbison worked on a new song , `` Running Scared '' , based loosely on the rhythm of Ravel 's Boléro ; the song was about a man on the lookout for his girlfriend 's previous boyfriend , who he feared would try to take her away .
