At age 40, Arnel Pineda lived every wannabe rock star's dream, middle-aged fan's fantasy and even one poor country's hope for financial success. A little more than five years ago, as videos of Pineda performing Journey cover tunes played on YouTube, he sat at home in the Philippines on the verge of giving up his dream of a singing and songwriting career. But those YouTube clips eventually earned Pineda an audition for rock band Journey, whose hits of the 1980s include “Who's Crying Now” and “Open Arms,” and he went on to become their lead singer in an unlikely career trajectory that is now part of Journey lore. A look inside Pineda's rise to fame and his struggles with rock ‘n' roll stardom are the subject of a documentary that is playing at this week's Tribeca Film Festival.
