Eventually got around to learning this... I'm doing it a tone lower, on the uke, so Eb intro; F verse; in-betweentro in F# but otherwise chords pretty much as suggested by Guest JM (thank you!)

BUT!!!

The fourth line in the second verse has bugged me since... well, since Joe's 2009 post. It surely must be "I think about your warm white sheets enfolding"

So a belated thanks to all contributors above and I can't wait to thrust it on an unsuspecting public!!
