I mean... the demo had 'more' lyrics with a different first line and is less repetitive with the paper line being used only once so it seems like it was a conscious decision to have a 'simpler' version on the record
This is interesting stuff. I remember reading that SG was originally conceived as a true follow-up to V&I, but that Morrissey changed his mind and instructed the band to pump up the volume and rock out. Listening to this demo reminds me of "Hated for loving", a better song for me.
