John Legend and Tony Bennett gave an impromptu lesson in harmonizing at the 2018 Grammys [1]. The duo, both multiple-time Grammy award winners themselves, were on hand to present the award for best rap-sung performance [2], but first, they gave us a verse from Liza Minnelli's song "New York, New York." The iconic movie theme song was later re-recorded and made even more famous by Frank Sinatra (he recorded a duet version with Tony in 1993). John and Tony's adorable onstage moment received rousing applause from the audience and was simply too pure for this world.

John Legend and Tony Bennett just did the ever-so-briefest a cappella of New York New York and it was 30 seconds of perfection #Grammys [3]
