It's a mashup of performances from artists that few people would think of putting together, like R.E.M. and Morris Day, Rick James and Duran Duran, Hanson and Cher. Filmmaker Ahmir “Questlove” Thompson's experience as a DJ taught him enough about beats per minute and musical keys to meld things seamlessly.

Questlove's newest documentary features interviews and clips from 50 years of musical performances on Saturday Night Live.

Lady Gaga, Bad Bunny, Arcade Fire, The Roots and David Byrne are among the scheduled performers for the event, hosted by Jimmy Fallon.

Timothée Chalamet performed two lesser-known Bob Dylan songs, in his own voice, as the musical guest as well as host of 'Saturday Night Live.'

Live is celebrating 50 years of late night comedy this year and one of the prime time specials that aired recently was 50 Years of SNL Music which featured past music performers since the show's debut in 1975.

Last night’s Saturday Night Live cold open featured an unexpected cameo when Lin-Manuel Miranda joined the cast during a skit set at the signing of the Declaration of Independence. The cast, dressed in 1700s attire, recreated the historic moment with a twist: Miranda, donning his iconic Hamilton costume, appeared onstage to thunderous applause.

The startling “cold open” for a documentary about 50 years of “Saturday Night Live” music is proof ... like R.E.M. and Morris Day, Rick James and Duran Duran, Hanson and Cher.

So, The SNL 50 Experience is a whirlwind of a time, and that’s putting it lightly. In the span of about 30 minutes, you are basically run through a mock show and a whole bunch of sets. It’s fast-paced, wild and very, very fun.

They throw you in a lake," says Silverman, who was a 22-year-old standup comic when she joined the cast as a writer and featured player, "and you just have to learn to swim.”

I never saw him laugh, but he told me he thought it was funny,” Johnson says of Driver. “I'm going to take him at his word.”

The concert will be followed on February 16 by a three-hour SNL50: The Anniversary Special. On February 15, NBC will re-air the very first episode of Saturday Night Live. The show debuted on October 11, 1975 with George Carlin hosting and Billy Preston and Janis Ian as the musical guests.

SNL50: The Homecoming Concert is executive produced by SNL producer Lorne Michaels and music producer Mark Ronson. The single night event will kick off the show’s celebratory weekend. On Sunday, Feb. 16, SNL 50: The Anniversary Special will air live at 8 p.m.
