Six months after Olivia Newton-John's death, actor John Travolta is paying tribute to his late Grease costar with a sweet recreation of their iconic "Summer Nights" duet in new Super Bowl commercial for T-Mobile.

Scrubs stars Zach Braff and Donald Faison pop up to sing new lyrics — touting the brand's services — to the tune of "Summer Nights" alongside Travolta, who also recreated several dance moves and signature poses he first popularized in a routine for the 1978 movie.
