A tribute to Obama's eight years of service to America, the song – originally sung by Lulu and featured in the Sidney Poitier film To Sir, With Love – boasts appreciative lyrics like "How do you thank someone, who has taken you from crayons to perfume? / It isn't easy, but I'll try" while also signaling an end of an era.
On the chorus, Strong sang, "If you wanted the sky I would write across the sky in letters that would soar a thousand feet high: To sir, with love."
The understated, moving tribute was reminiscent of SNL's post-Election Day rendition of "Hallelujah," with Kate McKinnon, as Hillary Clinton, performing the track alone while simultaneously remembering Leonard Cohen, who died earlier that week.
