"Don't Dream It's Over," originally by Crowded House
Miley Cyrus transitioned from teen TV stardom to the pop charts years before Grande, and the vocalists have shown each other mutual admiration. Last year, Cyrus invited Grande to one of her Backyard Sessions, where she often covers songs in a relaxed atmosphere, and the duo reclined on an inflatable couch to sing Crowded House's classic 1986 single "Don't Dream It's Over." Grande hits the signature high notes of the Antipodean ballad's chorus while Cyrus covers the "hey now, hey now" refrain. They chat about their animal pajamas during the instrumental bridge, causing Grande to miss her cue for the third verse, but recover nicely to finish off the song.
