Talking of Atomic Kitten, Eternal Flame beating Bootylicious to #1 was and still is a travesty. I know Bootylicious isn't DC's best remembered hit, but it was absolutely epic at the time. Much better than anything containing that weird auto-tuned yet strangely off-key long note in Eternal Flame.
I think the D.C. album had sold strong by that point, so was one of those victims of being a single after the release of a big album. Though the fact Atomic Kitten sold about 140k, that’s more than DC’s two number ones prior so maybe they wouldn’t have got the #1 anyway. I forget how much Whole Again made the Kittens flavour of the month.
