Yoko Ono and Sean Lennon helped The Flaming Lips close out Amnesty International’s “Bring Human Rights Home” concert last night at Barclays Center in Brooklyn. The duo joined the group for a take on Ono’s 1982 song “It’s Alright” before Lennon and the Flaming Lips did their thing with The Beatles’ “Lucy in the Sky with Diamonds” and their own “Do You Realize?” Ono and Lennon then returned—along with many of the night’s performers—for a group rendition of Bob Dylan’s “I Shall Be Released,” which included a verse sung by Lennon.

The Flaming Lips and their collaborators wrapped up a night that included performances by a wide range of artists, including Imagine Dragons, Cold War Kids, Blondie (who played their classics “One Way or Another” and “Call Me”), Cake, Lauryn Hill, The Fray, Bob Geldof, Colbie Caillat and Tegan and Sara. The show also featured an appearance by Nadya Tolokonnikova and Maria Alekhina of Russian activist punk band Pussy Riot, who were introduced by Madonna.
