Last Saturday’s episode of Saturday Night Live saw Cecily Strong and Sasheer Zamata sing “To Sir With Love” in a sendoff for President Barack Obama.

SNL PERFORMS MUSICAL SENDOFF FOR PRESIDENT OBAMA

It was a serious moment for the live comedy show, which has been outspokenly liberal throughout its existence. The women sang the song, which was from the 1967 film of the same name, which starred Sidney Poitier as an inner-city school teacher. The song became a hit for Lulu.

The tribute to Obama was concluded on a funny but bittersweet note, with Strong and Zamata holding up coffee mugs that said “World’s Greatest President.” And at the close, Zamata quickly adds, “Don’t go.” See the moment here.

SNL did a similar bit the Saturday following Hillary Clinton‘s loss to Donald Trump. As its opening number, the episode had Kate McKinnon as Clinton sing “Hallelujah,” with no jokes intertwined.

Strong teased the bit on Instagram the week before the show aired. It was a video of her lip-syncing “To Sir With Love,” with the caption, “Combining all my favorite things – lip syncing, loving Obama, old movies, and my dirty hair.”
