Billy Joel’s impromptu doo-wop performance just made our morning

When you get a bunch of musical geniuses together in one room, it’s no surprise that they’ll probably come up with something amazing. However, we never expected it to be this amazing when Jimmy Fallon, Billy Joel, J.K Simmons, and many others were hanging out during the commercial break. This group of talented men and women, seemingly out of nowhere, put together a completely unrehearsed doo-wop version of Billy Joel’s “The Longest Time.”

The group somehow managed to harmonize, switch on and off, and add their own crazy flourishes to the song, all without having practiced or even really discussed it beforehand. Billy Joel, of course, had a great solo, but Jimmy came in with his own verse and killed it as well. The sheer spontaneity and magic of it all is what made it so amazing, and it’s such a once-in-a-lifetime moment that we know none of them will ever forget.
