"Castles in the Air" is a great song. Thanks for posting that video - I always enjoy hearing McLean perform live because he likes to play with the timing of his songs and frequently sings behind the beat. I find that interesting. Other people, I'm sure, are annoyed by it. McLean has had many great, great songs, and in fact, nearly the entire American Pie album is at least as good as the title track. There is really only one, or maybe two songs that fall short. OTOH, he's also put out more than his share of dud records. I think he loves so many different styles that he's sometimes unable to resist dabbling in them rather than distilling their essence and letting that inform his songwriting. At his best, that's what he does, better than just about anyone. At his worst, he ends up with a collection of novelty songs. For anyone who wants to get into the heart of his best material, I'd recommend either AP or his two-disc live album, Solo.
