Before Journey kicks off their Summer tour with Pat Benatar and Loverboy, the documentary on Arnel Pineda, Journey's latest lead singer, will be screened for the first time.  "Don't Stop Believin': Everyman's Journey" will be at the Tribeca Film Festival in New York later this month. Next month, it will be featured at the San Francisco International Film Festival. The film focuses on Arnel's journey from being homeless in the Philippines to fronting one of America's most successful bands after guitarist Neal Schon discovered him on YouTube.
