I watched
Head on 6 November (the fiftieth anniversary of its premiere) and noticed a couple small things about some of the songs, but I waited to write about them until I listened to the soundtrack as part of my project of listening to all of the Monkees albums I have. That way, if I found more things to write about in the same songs, I could just write a single post.
I'm a bit unsure of my accuracy, but I think one of the lines in "Circle Sky" is "Here I stand, heavy man." When I watched Head, I noticed that the "heavy man" part of the line descends (E C# B A), almost as if the melody itself bends under the weight. "Heavy" is even sung with a melisma (E C# B), which emphasizes this descent.
