Jokes about Sugababes' revolving door line-up aside, the trio in whatever incarnation they were in always delivered a killer album lead single, didn't they?
Overload (2000), Freak Like Me (2002), Hole In The Head (2003) and Push The Button (2005) were all notable pop moments of the early Noughties, with three out of four topping the Official Singles Chart.
When it came to their fifth album header, it seemed the only option was to go big, teaming up with hit songwriter Cathy Dennis (Britney Spears, Kylie Minogue) on About You Now; a slick piece of electro-rock-pop that presented the group in a new light. Fitting, given that they were in the early stages of their third lineup change after the recent appointment of Amelle Berrabah to replace Mutya Buena.
The track was an instant hit, charging to Number 1 on the Official Singles Chart on its second week when it was made available to download, selling 34,000. It had debuted at 35 the previous week on physical sales alone, common practice at the time for single releases during the handover in formats.
About You Now spent four weeks at the summit, something no other girl group has managed to achieve since, though Little Mix have come close on two occasions: Black Magic and Shout Out To My Ex have both managed three weeks at the top spot.
To date, the song has notched up 626,000 combined sales, split between 470,000 downloads and 7.9 million streams. And it seems plenty of you are still enjoying it - last week it was downloaded 91 times in the UK and played 172,215 times on streaming services.
About You Now was to be the last Number 1 for Sugababes - the closest they would come again was in 2009 with (the distinctly less timeless) Get Sexy, the group's final single with the only founding member left Keisha Buchanan, who was ousted in time for their next single, About A Girl. Sigh.
Elsewhere in the Top 40 Shayne Ward landed the week's highest new entry with double (bop) A-side No U Hang Up/If That's OK With You, Ida Corr and Fedde Le Grand's electro-house banger Let Me Think About It zoomed to Number 5 from 64 the previous week, and Mark Ronson and Amy Winehouse's cover of Valerie was in the middle of its chart ascent, up from 41 to 12 (it would eventually peak at 2).
