Jeff Conway - Bobby Wheeler - Always found it funny in an ironic way the guy who played a struggling actor in the show would go on to be the 'least famous' of the bunch. He did the movie Grease, and then did well in the show Babylon 5.
Jeff Conaway had addiction issues like Ignatowski. He was on Dr. Drew's sobriety show, I think. He was one of the best actors on
Taxi. His turn in Grease was memorable. Shame.
Yes, he was on Dr. Drew, who has been called exploitative of people because of the use of reality television for the treatment and care for addicts. I'm sure he claims it's a public service. I don't know how I feel about it, but on the show Conaway invoked feelings of pity and sadness. He was permanently stuck and had little control over his life. It was painful to watch.
