Something/Anything? (1972). There must be a god, because, against all odds, I have learned to play this song on my acoustic guitar. It took a while, but, with the help of the Internet, I figured it out. I was 15 years old when this song came out, and I have loved it immensely for the past 43 years. Since getting the idea to learn it on guitar (a week ago today, during a bike ride), the song has been going around in my head nonstop, even at night while I'm sleeping. It is imprinted on my brain, probably permanently. In case you're wondering, I sing the song as well as play it on guitar. I'm not the greatest singer, but I enjoy singing and am getting better at it with each passing day. The song consists of 17 different chords, every one of them a seventh (for example, C#m7 and D#maj7). Todd Rundgren is a genius.
Addendum: Here is information about the song. Here is the flamboyant Todd performing on the Midnight Special. Here he is playing the song on electric guitar.
