Suzi Quatro and Chris Norman teamed up for a Glam double-act when they sang this catchy Chinnichap number, Stumblin’ In.

When this cheesy romantic duet came out in 1978 I was a diehard punk and, despite a teenage crush on Suzi Quatro, I would never have admitted liking it.

All these years later, of course, it’s a guilty pleasure. Not that I believe in the idea of guilty pleasures – I’m happy to admit I love it.

Like nearly every song composed by Chapman and Chinn it’s absolutely contagious: a banger (as nobody said then) and an irrepressible earworm (ditto).

I love this clip off a German TV show because Suzi and Chris Norman, the smoky-voiced singer from Smokie, act it out like starcrossed lovers.

As far as I know they weren’t…  but they do a great job of convincing us as they sing their deut.

Apparently Chapman, who had written hits for both artists, was at a party in Dusseldorff where he found them singing together at a party, Suzi playing her bass and Chris with his arm around her shoulders.

“I thought what a fantastic duet they’d make because they looked so great together,” he recalled. “The next day I was in the studio with Suzi and during a break I came up with the line, ‘Our love is alive’…

“I looked at Suzi and said ‘What about this, with you and Chris? Wouldn’t it be great?’ – and she said it sounded fantastic.” 

Strangely, although I remember it so well, the single wasn’t technically a hit in the UK, peaking at No.41 but it did better in America, reaching No.4 – giving Suzi her only US hit single.

And it got a new lease of life when it featured in Paul Thomas Anderson’s coming-of-age comedy Licorice Pizza a few years ago.
