For the most part, the song is straightforward love song, the narrator declaring his feelings for Eileen. But the first verse is about Johnny Ray. The first part of the video is too.
Johnny Ray isn’t mentioned in the rest of the song, and the song itself isn’t in his style. Kevin Rowland presumably set out to write a song about Johnny Ray then got distracted and ended up writing a completely different song, but left the first verse in because… well why not? It didn’t prevent the song from being a huge hit.
So, I’m wondering; what other well-known songs do something like that?
I’m not talking about songs like I am the Walrus, where all the lyrics are incongruous, nor am I talking about “plot twist” songs where something unexpected happens but it’s still part of the same story. I’m asking about songs where part of the lyrics are about a completely different topic. I’m sure there are other obvious examples but Eileen is the only one springing to my mind right now.
