You can write a letter, like XTC did. And perhaps you'll get an answer. The song is pretty straightforward, if you spend any amount of time with it. Musically, it's a pretty little pop gem that XTC are known for (by those who know). Unfortunately, XTC isn't known for commercial success, which means their following basically consists of music nerds like me.
Dear God wasn't even included on the original release of Skylarking. It was a b-side of the album's first single, Grass. Dear God became something of a hit which led to the pulling of Mermaid Smile and the re-releasing of the album. Also, there was a lot of friction between Todd Rundgren, the album's producer, and Andy Partridge, who is the main songwriter for the band. In spite of that, Skylarking is considered one of XTC's best albums.
