The biggest difference seems to come at the end, but the Glee version is very faithful to the original with some simple alterations here and there. Jane Lynch does a great job as a stand in for Madge, even if her dance moves seem a little overly rehearsed. The vocal track is all Sue Motherfucking Sylvester, but the spirit is all Madonna. Caution: this video will definitely make you excited for next week's all-Madonna episode of Glee and may possibly turn you gay. Thanks to commenter Rina for the idea.
