Janelle Walker shuts down a white heckler with hilarious “YMCA” remix: What happened? As Walker launched into the opening lyrics, singing, “Young man, there’s no need to feel down,” the man reached over and touched her keyboard. Without missing a beat, she instantly rewrote the lyrics on the spot, warning him through song: “Young man, I will kick your a– out…”The crowd laughed, but the interruption didn’t end there. A short time later, the man approached Walker again, this time from behind. She went too far… Blah blah blah.”
