Carly Rae Jepsen’s catchy “Call Me Maybe” continues to win over the hearts of countless Internet music lovers, topping Billboard‘s Digital Songs chart this week and the iTunes Store singles chart last week.

Music website Popdust, though, wants to keep the tune’s momentum flowing with its clever mashup of 75 lip-dubs, vocal covers, instrumentals and dance numbers.

We spy loads of famous faces in the clip such as Katy Perry, Justin Bieber, Selena Gomez, James Franco, Joan Rivers, Jessie J and Kathie Lee Gifford. Lip-sync king Keenan Cahill makes an appearance as do cover-song heavyweights Sam Tsui, Cimorelli, Ahmir and Tanner Patrick, who recently turned an iPad into a drum machine to put his spin on Perry’s “Part of Me.”

Of course, the mashup also stars Harvard University‘s baseball players and Southern Methodist Univeristy’s female rowing team (see their viral dance renditions below).

“If you thought the song was intoxicating before, just wait till you see it performed on accordian, lip synched by three shirtless dudes in a river, and danced to by an overzealous girl alone in a closed Burger King,” reads the video’s YouTube description. “You will see these people and hear this song when you close your eyes at night, and again as you wake up in the morning.”

The song’s original video has 76 million views while her second video (featuring cameos from Bieber, Gomez and Ashley Tisdale) has nearly 40 million.
