The new documentary Don't Stop Believin': Everyman's Journey tells the story of Arnel Pineda, a Filipino singer who rose from a YouTube sensation to the frontman of Journey. Directed by Ramona S. Diaz, the film chronicles the challenges Pineda faced before he joined the band in 2007, as well as his efforts to fill the shoes of the band's much-beloved frontman, Steve Perry, and embark on a massive world tour. Now you can check out this exclusive clip in which Pineda meets Jason Scheff – who replaced Peter Cetera as Chicago's bassist in 1985 – and the two bust out an impressive, spontaneous duet of Chicago's "Will You Still Love Me?"
