Lady Gaga channels Cher (that wig!) in her latest video for "Bang Bang (My Baby Shot Me Down)."
The live recording is part of the upcoming PBS special Tony Bennett & Lady Gaga: Cheek to Cheek Live!, which taped in July. Decked out in an all-red ensemble and sans Bennett, Lady Gaga shows off her incredible vocals -- save for a small band and pianist, she's alone on stage. No backup dancers or elaborate set pieces here.
