WWE Video: C.M. Punk leads the WWE stars in singing "Happy Birthday" to John Cena

Additional video footage of the John Cena birthday party that was held after Monday's WWE Raw can be viewed at Youtube.com/watch?v=0pFtVadshAY&feature=relmfu.

Powell's POV: C.M. Punk leads the crowd and a stage filled with WWE personalities in singing for Cena. I got a kick out of Mark Henry standing on the stage with his arm crossed while everyone else, including Vince McMahon, clapped for Cena.
