Concertgoers attending The Eels performance over the holiday weekend were surprised by a special performance by Steve Perry.  The Journey frontman joined the indie-rock band to sing their 200 hit "It's a Motherf---er."  Perry loves the profanity-loaded song likely because of the meaning behind it.  he Eels Mark Everett draws inspiration for his music on personal tragedies, such as losing his mom to cancer.  Perry lost his girlfriend to cancer just over a year ago.

Perry told the crowd at the Fitzgerald Theater, "I love that song… When I first met [Everett], I said someday I wanted to sing that song. And tonight is the first time I've ever sang it."

Following his performance of The Eels song, Perry joked "I don’t know why the Eels don't do my music," when Everett replied, "We were just waiting for you!"  Then the crowd was treated to Journey's "Open Arms" and "Lovin', Touchin', Squeezin'" which Perry hadn't performed on stage in over 25 years!  Check out the performance in the video below, just remember there is profanity in some of the lyrics.
