Green Day frontman Billie Joe Armstrong and singer Norah Jones performed together in a rare concert on Wednesday night.
The duo played songs from their 2013 album, Foreverly, a collection of songs inspired by Songs Our Daddy Taught Us, an album released by The Everly Brothers in 1958.
The pair played at The Bowery Electric in Manhattan, New York, to 200 fans on Wednesday, as the concert wasn't widely announced.
Armstrong played guitar and sang, while Jones switched between guitar and piano. The band also included drums, a standup bass and, at times, a violin and a harmonica.
No other performances were announced.
