“Saturday Night Live” returns on Saturday with another new episode, this time hosted by “SNL” alum Jimmy Fallon who will be joined by musical guest Harry Styles. Tonight’s live episode will begin a new trend for “SNL,” which will be airing the final four episodes of Season 42 live across the nation.

Fallon filmed a number of promos with Styles who will be making his solo debut on the April 15 episode. In typical Fallon style, the host can be seen laughing as he and the “Sign of the Times” singer snap their fingers to a jazzy soundtrack.

Following the April 15 episode, “SNL” will take another short break and return on May 6 with an episode hosted by Chris Pine. Melissa McCarthy will then return to host on May 13 while Dwayne Johnson will host the season finale on May 20. The final four episodes will air at 11:30 p.m. EDT, 10:30 p.m. CDT, 9:30 p.m. MDT and 8:30 p.m. PDT on NBC.

“‘SNL’ — enjoying its most popular season in two decades — is part of the national conversation, and we thought it would be a great idea to broadcast to the west and mountain time zones live at the same time it’s being seen in the east and central time zones,” said NBC Entertainment Chairman, Robert Greenblatt.

According to Greenblatt, having the episodes air live across the country will be great for viewers. “That way, everyone is in on the joke at the same time. Kudos to Lorne Michaels, the producers and cast for making SNL one of the most relevant and anticipated shows in the zeitgeist,” he said.

Fans of Harry Style can expect the singer to perform the lead single from his upcoming self-titled as well as one more track. The singer revealed the tracklist for his debut album on Thursday, revealing the project will include 10 songs.
