Legendary Journey vocalist Steve Perry made his return to the stage over the weekend after an 18-year hiatus that had some Journey fans wondering if he was even still alive.  Perry joined the alternative rock band the Eels onstage last Sunday, performing their song "It's a Motherfucker" to the raucous approval of Eels fans.  The performance was filmed by a fan in the audience, and appeared on YouTube earlier this week.  Check out the clip below.  Perry left Journey in 1997 after suffering a hip injury, living a relatively private life ever since.  Since 2000, Journey has been fronted by Arnel Pineda, but the Phillipines-born singer revealed on Twitter that he wouldn't stand in the way of a Perry return to the band.  "He should come back. His voice is still there. I missed that voice," Pineda replied after a fan sent him a link to the YouTube video of Perry's performance.
