There are two reasons why this was a big hit single in 1976. It’s an undeniably catchy song, with its mix of acoustic and electric guitars and a tuneful melody. But the big reason is the arresting sight and sound of a bloke piping his electric guitar through his own mouth.

It creates a kind of home-made effects pedal, as well as a peculiar sight with Frampton making funny faces to bend the notes.

It’s an appealingly novel sound, though you wouldn’t want to hear too much of it. Which may explain why Frampton, who had been slogging away for a decade before this, and has continued to slog away ever since, is something of a one-album wonder with his concert LP Frampton Comes Alive.

I seem to remember reading that as a result of his penchant for channelling electronic vibrations through his mouth, Peter Frampton’s teeth all fell out afterwards

I kinda liked this song at the time, and I remember a lot of people I knew bought the album – Frampton Comes Alive.

With a cover photo of the angelic Frampton in mid-solo, it was a bit of a Thing for those who liked their virtuoso guitarists, and their rock music leavened with a smooth melodic veneer.

I was thinking this might be the only song I know by Frampton, who started out in a Sixties group called The Herd (who I don’t know at all – and, listening now, am glad to have avoided) and Humble Pie, the group Steve Marriott formed after The Small Faces, who I know a little bit.

Then I looked him up and realised he has another called Baby I Love Your Way, which is similarly melodic and a bit dirgey, with a pleasant mix of acoustic and electric guitars, and another show-offy bit in the middle, in this case involving electric piano rather than guitar.

I also learned that in the Eighties he played on an album called Never Let Me Down, by one of his old schoolmates from Beckenham – David Bowie.
