John Travolta’s Surprise Welcome Back, Kotter Reunion With Lawrence Hilton-Jacobs — WATCH

Vinnie Barbarino and Freddy “Boom-Boom” Washington reunited this week when Welcome Back, Kotter vet Lawrence Hilton-Jacobs surprised long-ago “classmate” John Travolta on the red carpet at the TCM Classic Film Festival.

Back in 2011, Kaplan, Strassman, Travolta, Hegyes, Hilton-Jacobs and Ellen Travolta (aka John’s big sister, who recurred as Horshack’s mother) were on hand when Kotter was honored at the TV Land Awards.

Gabe Kaplan played titular teacher Gabe Kotter, while a pre-Urban Cowboy/Staying Alive Travolta played too-cool-for-school heartthrob Vinnie and Hilton-Jacobs played hoops star Freddie.
