Everyone is a star in their movie

Biography of Pete Walli of Kingston Wall. The guy killed himself so that gives him and the band a cult status. To me, they never were anything special, to be honest, I never gave him a thought when he was alive and I didn't particularly like the music. Walli was a rock musician who wanted to become a star, desperately, but that never happened. He was gifted, granted, and he did his utmost, but not enough and in the end he was a failed rock'n'roll star with a drug problem. He also went all crazy on weirdo religion before the band's third and final album, and his untimely death, so the premise is kind of interesting.
