Welcome Back, Kotter (1975 - 1979)
An Emmy-nominated hit about a high-school teacher who returns to his Brooklyn alma mater, James Buchanan High, and is saddled with a class of misfits known as the Sweathogs. The series was based on the real-life experiences and stand-up of Gabe Kaplan, who was the show's cocreator. The theme song, written and performed by John Sebastian, topped the charts in 1976. The series was a star-making vehicle for John Travolta, who, during its run, did `Saturday Night Fever' and `Grease.'
