In July 1957, NBC returned the program to a talk/variety show format once again, with Jack Paar (who left his role as morning show host on CBS to join NBC) becoming the new solo host of the show. Under Paar, most of the NBC affiliates that had dropped the show during the ill-fated run of "Tonight! America After Dark" began airing the show once again. Paar's era began the practice of branding the series after the host, and as such the program, though officially still called "Tonight", was also marketed as "The Jack Paar Show". A combo band conducted by Paar's Army buddy pianist Jose Melis filled commercial breaks and backed musical entertainers. Paar also introduced the idea of having guest hosts; one of these early hosts coincidentally was Johnny Carson. It was also one of the first regularly scheduled network shows to be telecast in color beginning sporadically in September 1957, with regular color broadcasts beginning in September 1960.
