Quick Question...

I would like to preface this by admitting that yes, I am a bit of a geek for Barry Manilow. That being said, I was more than a little perplexed by the tape found in Amy's car: "Tropical Nights" by Barry Manilow, an album that I didn't even know existed! However, after doing some research, I discovered that Manilow does not even have a song with this title, let alone an entire album. After breathing a sigh of relief that I was not missing an integral part of Manilow's extensive canon, I began to wonder why Chris Ware made this error. It would be foolish of me to say that it was unintentional, because I think we all know that nothing in "Jimmy Corrigan" is unintentional. I really have no answer to this question, and was wondering if any of you had any thoughts about this.
