NBC is celebrating 50 years of Saturday Night Live by honoring all of the musical guests in a new three-hour special.

Ladies & Gentlemen... 50 Years of SNL Music is airing on NBC on Monday night (January 27) and will feature untold stories behind the culture-defining, groundbreaking and news-making musical performances, sketches and cameos of the past 50 years.

The special will showcase interviews with musical artists, cast, writers, producers and more who have been part of SNL's legacy.

Oscar-winning filmmaker Questlove, who leads the band on The Tonight Show Starring Jimmy Fallon, directed the special with Emmy Award winner Oz Rodriguez.

"Everyone knows the most famous SNL appearances, whether it's Elvis Costello, Prince or the Beastie Boys, but they're the tip of a huge iceberg," Questlove said. "The process of going back through the incredible archival footage was like being in a time machine, DeLorean or other. I'm so happy I went on the trip and now get to share it with everyone."

We have a full list of the musicians and SNL alum who are appearing on the special.
