Number 1 today in 1999: Eiffel 65 deny S Club 7 a second Number 1

It's 15 years since Eiffel 65 painted the town Blue (Da Ba Dee) and stopped S Club 7 and Shania Twain hitting Number 1.

Back in the '90s, September meant only one thing on the Official Singles Chart: it was the month where you got to hear what everyone had been dancing to on holiday. Not wanting summer to end, UK pop pickers would extend their holiday by buying the big hits they'd been hearing on the Costas. And 15 years ago today, a little-known dance outfit called Eiffel 65 were benefitting from that holiday feeling.

First finding success on mainland Europe, Italian dance group Eiffel 65's first UK hit Blue (Da Ba Dee) was somewhere between novelty hit and serious dance tune. An instant hit not just with holidaymakers but everybody who it head it "back home", the song initially charted in the Top 40 based on import sales alone – which is pretty impressive.

On full release in the UK, it went straight in at Number 1, deposing another poolside favourite, Vengaboys' We're Going To Ibiza! Demand for the track was pretty high – Blue (Da Ba Dee) sold over 220,000 copies in its first week on sale! This week in 1999, it was spending its second week at Number 1, which was bad news for seven talented young singers from a little closer to home…

S Club 7 already had one Number 1 on their belt, thanks to debut single Bring It All Back, so the chances of follow-up S Club Party achieving the same looked pretty high. The infectious track, which has one of the best middle-eights in pop ever, had some pretty serious competition, however. Apart from the current chart-topper, it had to beat that week's other big releases.

Shania Twain, fresh off the back of her huge hit That Don't Impress Me Much, was unleashing the hen party classic Man! I Feel Like A Woman! and pop princess Britney Spears was set to release the third single from her debut album – the Pop Gem (You Drive Me) Crazy.

Sadly, although everybody wanted to see Bradley swing and Rachel do her thing, S Club 7 couldn't break the spell cast over the UK by Eiffel 65 Blue (Da Ba Dee) was still selling strongly. When the final whistle was blown that week, Eiffel 65 were way ahead, outselling Jo, Hannah, Bradley, Jon, Rachel, Paul and Tina by two to one.

If you're going to lose out on the Number 1 slot, you want to do it to a worthy winner, and the S Clubbers certainly did – Blue (Da Ba Dee) went on to sell over a million copies! Only one more hit was on the way for Eiffel 65; they took Move Your Body to Number 3 in early 2000.

For S Club 7, of course, it was just the beginning. S Club Party was the second of 11 consecutive Top 10 hits for the band. They scored four Number 1s, would ditch the 7 when Paul left in 2002, and they had their final hit with Say Goodbye/Love Ain't Gonna Wait For You in summer 2003. S Club Party has sold over 300,000 copies in the UK.

So where did Shania and Britney land in the chart that week? Read on…

3: Shania Twain – Man! I Feel Like A Woman!

Let's go girls! A fourth Top 10 for Shania and her joint-highest chart peak. Five more Top 10s would follow, with the last being almost ten years ago – her duet with Mark McGrath, Party Of Two. These days, Shania concentrates on her residency in Las Vegas, but hopefully one day she'll get back to making a few hits. Man! I Feel Like A Woman! has sold over 440,000 copies in the UK.

4: Lou Bega – Mambo No. 5 (A Little Bit Of…)

See what we mean about September being the month of summer holiday hits? Former chart-topper Lou Bega never again had a Top 40 hit in the UK, but he can console himself with the fact that Mambo No. 5, based on an old tune from the '40s by Pérez "Prez" Prado, has sold over 950,000 copies in the UK.

5: Britney Spears – (You Drive Me) Crazy

STOP! Britney's third Top 10 hit would go no further than this position, and would be followed up by Britney's second Number 1 Born To Make You Happy. 20 more Top 10 hits were on the way. Altogether, Britney has scored six Number 1s. (You Drive Me) Crazy has sold over 280,000 copies in the UK.

The rest of the Top 10:

6: Sun Is Shining Bob Marley
7: VengaboysWe're Going To Ibiza!
8: DJ JeanThe Launch
9: Paul JohnsonGet Down
10: LollyMickey
