Peter Gabriel’s solo debut single. The structure of the song reminds me of the old blues principle of question and response - the significant and catchy riff followed by the melody phrase. Odd 7/4 measure throughout, except for the last two bars, before the intro is repeated.
Not very complicated, except that the 7/4 measure requires some time to get used to (at least for me). Sometimes the melody starts with the final note of the riff. Same for the last note of the verse, which rings into the riff again.
