The pair debuted the video on The Tonight Show Starring Jimmy Fallon on Monday, which begins with Fallon waking up, noting, "March again, it's another morning / Every day, like the one before / March again, and it's been a full year, of waking up to say -- I'm bored. Indoors. I'm bored. I'm bored, indoors."
Fallon goes on to note the endless Zoom meetings, TikToks and more that have become synonymous with quarantine. Legend then makes a spectacular appearance.
"Oh, isn't this amazing? / Wasn't it just March 2020?," he sings. "I've forgotten what time means / And I haven't waxed my chest since quarantine week three."
Later, the two bring it home, singing together, "No I can't believe it's been a year/ It really has been quite a year / I can't believe it's really March again."
At the start of quarantine, Fallon and his fellow late-night hosts had to learn how to run their shows from home. Here's a look at how they pulled it off!
