Some of the most iconic music moments of the last 50 years (think Sinead O'Connor, Ashley Simpson and Elvis Costello, to name a few) happened on the hallowed stage that is 30 Rock, where "Saturday Night Live" is filmed. As "SNL" is celebrating its 50 years on NBC, the network is airing the documentary "Ladies & Gentlemen… 50 Years of SNL Music" on January 27th. The doc was directed by GRAMMY and Academy Award-winning filmmaker Ahmir “Questlove” Thompson and Emmy Award winner Oz Rodriguez. The three-hour special will showcase interviews with musical artists, cast, writers and producers who will tell behind-the-scenes stories about the show's most famous musical moments. "Ladies & Gentlemen… 50 Years of SNL Music" will air next Monday at 8pm on NBC, and will stream the next day on Peacock.
