The Backyard Sessions are a series of music videos released by Miley Cyrus on YouTube in 2012, 2015 and 2020. The 2015 series coincided with the formation of Cyrus's philanthropic organization, the Happy Hippie Foundation, and were billed as "Happy Hippie Presents Backyard Sessions". In a May 15 video, Cyrus was joined by Ariana Grande for a cover of "Don't Dream It's Over" by Crowded House. Cyrus wore a unicorn onesie, while Grande wore a mouse onesie. The pair reprised the performance at the One Love Manchester benefit concert organized by Grande in June 2017.
