Post Malone and Jimmy Sing "Seven Drunken Nights"
Jimmy Fallon Post Malone serenade us with bar anthem "Seven Drunken Nights". Backed by a band, the duo swapped verses before coming together for the rousing chorus. In the clip, each holds (and sips from) a pint of beer while the song unfolds. They urge the audience to clap along during the chorus, resulting in a boisterous finale.
