So far, S Club 7 have teased us with their two number one singles: a cheesy TV show theme, and a festive ballad. Okay records, but no real proof of why they were the turn of the century’s finest tween-pop bubblegummers.

Don’t Stop Movin’, by S Club 7 (their 3^rd of four #1s)

1 week, from 29^th April – 6^th May / 1 week, from 20^th – 27^th May 2001 (2 weeks total)

Until now. Because here is their undisputed (by me) best song: an unapologetic disco-pop banger. Uncontrollably catchy, unarguably wholesome, utterly lacking in edge. But who needs edge? Not S Club. Not anyone, really, when they have such a complete and utter floor filler. I can genuinely not imagine a party where ‘Don’t Stop Movin’’ would not get people dancing (and if there is then I don’t want invited).

Musically, this smooshes the past twenty-five years of pop music into a blender and comes up with a balance that works. The strings are disco, the beat is a ‘Billie Jean’ rip off (not a sample, as some claim), and the chorus is pure nineties bubblegum. For 2001, you could claim that it sounds old-fashioned. I’d rather go with ‘timeless’. There’s even a vocoder, for the fabulously naff Don’t stop movin’ to the S Club beat… coda, giving things that Daft Punk chic.

Bradley McIntosh is on lead vocals here, for the verses. (I have seen Bradley perform this live, and to this date he remains the only chart-topping artist whom I have touched/got an autograph off). Then regular lead Jo takes over for the bridge, which is the part of the song that seals its classic status. And which, listening to it now, owes a big debt to Madonna’s ‘Vogue’. Right here on the dance floor is where you got to let it go… Her vocals ahead of the final chorus are actually fairly spectacular.

I often claim that British pop songs lagged behind their US cousins at this time, which they did. But ‘Don’t Stop Movin’’, while completely British in its production and tone, can compete in terms of quality with almost anything that Britney was putting out at this time. And if I had to choose between this and the overly earnest Destiny’s Child record it knocked off top spot then there’s no contest.

There will be those that argue for ‘Reach’ as S Club 7’s best song, and it is a debate that causes deep divisions. ‘Reach’ is a great pop song, if a little too goody two shoes for my liking. But the real reason why ‘Don’t Stop Movin’’ is S Club’s greatest song, and not ‘Reach’, is that while both could happily be played at a primary school disco, only one could be played in a respectable nightclub. This one.
