Kirsty MacColl, the daughter of folk singer Ewan MacColl, sang on this track and made some other contributions as well. Jim Kerr told Songfacts: "We used to live in this hotel in London, and everyone would come and hang around. And there was this younger girl called Kirsty. She liked Simple Minds and she would hang around, but you know, she would piss us off. She was hanging around, hanging around, and we'd say, 'Get out of the way! Go home, you're young.' Whatever. She was a ballsy little thing. She was smarter than all of us, and she could just kill us in one line. And that would make us laugh, and then we would let her in the gang.
So, she would come down to the studio. We knew that she was the daughter of Ewan MacColl, albeit they were estranged. But anyway, we knew that she had roots. And we knew that she played a bit of acoustic guitar and did a bit of singing. We allowed her to come down and hang around, and as soon as she'd get in, she started bossing people around.
We were a bit lost on that track. We knew it had a great melody, but the arrangement was kind of puzzling us. And with a stroke, she said, 'Do this. And put that there. And put that little bit at the end.' And we were like, Listen to you!
I've got great memories of that. And, of course, she said, 'I want to sing on it, as well. Let me do this thing.' And she went."
