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.

On SNL, he opened the show with three musical pieces played to near perfection, and went on to show his acting chops with comedic skits. He was introduced by SNL and Hollywood star Adam Sandler, in response to a joke made by Nikki Glaser at the recent Golden Globes.

Chalamet was joined on all three numbers by James Blake on keys. The British singer/ producer later took to Instagram and wrote: “Surreal and fun to play Saturday Night Live with Bob Dylan... I mean Timothee Chalamet. Congrats to Timmy on everything.

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.”
