This is the greatest disco song of all time; no argument about that. And one of the greatest songs of all time. I usually tend towards the view that these things are a matter of opinion but in this case I hope we can all agree.

Incredibly, I Feel Love started life as the B-side of a single off Donna Summer’s fifth album.

In May 1977 she released Can’t We Just Sit Down (And Talk It Over). It wasn’t a big hit. Two months later the single was re-release with the sides flipped… and topped charts all over the world.

Written, produced and played by Giorgio Moroder and his oddly unsung English partner Pete Bellotte, it catches you from the moment it begins.

Donna Gaines had already had moved to Munich from New York in 1968 to appear in the stage musical Hair.

She was working as a model and session singer when she met Moroder and Bellotte while working on a recording with Three Dog Night.

They took her under their wing, changing her name and releasing four albums.

But it was not until the final track of her fifth album, I Remember Yesterday, that they truly struck gold.

Aiming for a futuristic sound, they borrowed a Moog synthesiser from the classical composer Eberhard Schoener.

It was his assistant Robby Wedel who introduced the duo to the magic of a click track and a sequencer.

The only ‘instrument’ on the song is the drums of English session man Keith Forsey.
