. "Welcome Back, Kotter is an television sitcom which aired on ABC from 1975 to 1979. The show followed Mr. Kotter (played by Gabe Kaplan), a teach who returns to his high school alma mater in New York City, to teach a class of remedial students, known as the \"Sweathogs\". The series turned John Travolta into a teen idol, but by the third season the actors playing the high school aged Sweathogs ranged from 24 to 29, and the show was cancelled the following season. The theme song was ranked by TV Guide as one of the 50 All-Time Favorite TV Themes, and the character Vinnie Barbarino was ranked as #83 in Bravo's 100 Greatest TV Characters."@en .
