Musically, there's a lot going on in this song. After the line, "as my heart began to fall," the rhythm changes completely, going into an instrumental section as we enter the dream sequence. Graham Gouldman's first attempt at the music was deemed "too bland," but they livened up à la Paul McCartney in "Band On The Run
"It just goes on," Eric Stewart said of their first attempt. "On one plane, your verses and your middles and your der-der-der, they're all going on the one plane. What it needs is someone to go bash
on the side of your head."
So Stewart and Gouldman changed the rhythm completely and "put two whacking great guitar solos in there, in the middle of this quiet, soft, floaty song." The end result was, "this lovely interesting song with the whacking guitar solos in it."
