The song played during the final scene is 1987s "The Time of My Life", by Jennifer Warnes & Bill Medley.
In this episode they reference Patrick Swayze being a bouncer (in Roadhouse) but that movie didn't come out until 2 years AFTER Dirty Dancing. 1987 and 1989
In the scene at the school dance where the dance from Dirty Dancing is reenacted, professional dancers made to look like Erica and Geoff do the lift. If you watch closely, you can see it is clearly not Erica and Geoff.
