Jeff Conaway: Actor best known as Kenickie in 'Grease' and Bobby

Starring as the swaggering, leather jacket-wearing heartthrob Kenickie, alongside John Travolta, in the film version of the hit musical Grease brought Jeff Conaway global fame. Cinema audiences were quick to learn of Kenickie's two biggest loves – fast motors and fast women – in an early scene where he has sex in the back of his car with his girlfriend, Rizzo (Stockard Channing). Kenickie is a leading light in the high-school T-Birds gang of greasers and sidekick to Danny Zuko (Travolta), whose rekindling of a summer romance with Sandy Olsen (Olivia Newton-John) is the central story in the 1978 film. Conaway had already played Danny in the stage musical on Broadway but had to make way on screen for Travolta, who was hot property following his starring role in the film Saturday Night Fever.
