Miley Cyrus was the only guest on Late Night with Jimmy Fallon last night, and once again The Roots demonstrated that theyâre the most gifted musicians in late night, if not all of television. This a cappella rendition of âWe Canât Stopâ, which features the band as well as Miley and Jimmy in a Brady Bunch-style split screen, is simple but undeniably charming. Though for my money, itâll never rival their cover of the Sesame Street theme.
