Part of Me (Katy Perry song) [SEP] Live performances
"Part of Me" was given its first live performance on February 12, 2012, at the 54th Grammy Awards. The performance began with "E.T." with dancers and a singer who appeared to be Perry on a darkened stage. It ended partway through the chorus as electronic sound effects and the lights and sound suddenly went out, implying technical difficulties. Wearing sunglasses and a metallic bodysuit with the appearance of golden armor, a blue-haired Perry, slowly singing the first part of "Part of Me," descended from the roof of the venue in a transparent cube, revealing the singer on the stage below to be a body double.
