This is a song that is very easy to listen to and not think very much about. It's a generic '70s pop song about trying to make it big in Hollywood. It's nothing revolutionary, it's a sentiment that still rings true today, people are still trying to be a Someone rather than a nobody. But if you really listen, and think about the lyrics, it becomes rather tragic.
This is a song that tells the story of someone up and moving to California, with little thought or planning he spends the last of his money on a plane. The culture around actors, Hollywood itself, the bountiful opportunities California seems to offer drives him to ditch his old life for the possibility of stardom.
I think it's really heartbreaking if you actually give it a listen. Even the chorus, when it rains it pours, when it's bad it only gets worse. It's meant a great deal to me ever since I first listened to it, though I don't particularly know why.
