The PS22 Chorus, the elementary school choir that became a sensation after their YouTube videos went viral, performed last night (April 20) at the Tribeca Film Festival with some very special guests. 

Katy Perry recently surprised the singing troupe, but last night saw members from the iconic band The Bangles join their line up for an exciting rendition of 'Walk Like An Egyptian'. 

Susanna Hoffs and Vicki Peterson took the stage with the young choral group and they sang the song together. Watch the video of the performance here:
