WATCH: Club-goer tackles singer in front of horrified audience
We're not exactly sure why this happened but it's hilarious to watch.
Singer Jay Murray was belting out Neil Diamond's 'Sweet Caroline' while strumming his guitar, but that quickly ended in chaos as a man jumped onto the stage and pulled him by the legs.
The unidentified bearded man, seen wearing jeans, walked onto the stage, flipped the singer in the air and slammed him into the floor of the stage where The Beatles first shot to fame.
The attacker then proceeded to kick Jay Murray as he lay on the floor, before fleeing.
