Yes, Saturday Night Live is still awesome. But, in case you’ve missed out on previous seasons, tonight is your night to catch up.

Tonight SNL premieres, and it’s 40th season is bound to be full of big laughs and an even bigger audience. Here’s what you can expect, thanks to Huffington Post:

At least three cast members have been replaced. That means no more John Milhiser, Noel Wells, and Brooks Wheelan. Mike O’Brien, who was promoted to cast member at the beginning of season 39, will  also be replaced. He’s not leaving the show entirely, though. O’Brien will be returning to the writer’s room of SNL this season.

Nasim Pedrad, a five-year veteran of the show, announced her departure earlier in the year. She’s starring alongside former SNL writer John Mulaney on the upcoming Fox sitcom Mulaney.

SNL’s longtime announcer, Don Pardo will be missed by many fans both old and young. He passed away at the age of 96 earlier this year. His voice was an ubiquitous fixture at SNL, proclaiming “It’s Saturday Night Live!” for all 39 seasons and working for NBC for a notable 70 years.

That means new faces and a new voice for SNL’s 40th season. That voice comes in the form of Darrell Hammond (an alum from 1995-2009). You might remember Hammond as playing Bill Clinton, Al Gore, Donald Trump and Sean Connery.

One new face heading for the SNL stage is twenty-year-old stand-up comedian Pete Davidson, who joins former SNL writer Michael Che as cast members. Davidson appeared on the Fox comedy Brooklyn Nine-Nine and has performed on Jimmy Kimmel Live.

Che left SNL at the end of the last season and now returns as co-anchor for SNL’s Weekend Update segment.

On October 11, 1975, Saturday Night Live was broadcast for the first time. Now, 40 years later, the show is an institution showcasing pure comedy, political satire and the skewering of pop culture and current events.
