As you may remember, the band imploded at the height of their fame in 2004 over the disputed ownership of a combat jacket. Songwriter Shaznay Lewis had been allotted it for a photo shoot, but Natalie Appleton decided she wanted it instead. After the squabble, the pair wouldn't speak for years.
"I would never in a million years have put money on the group ending over a jacket," Shaznay told The Guardian in 2004. "But when that incident happened, it fired up so strong, it had to be over... And the way I was then, the state we'd got into then, there was no way she was getting that stupid jacket."
So the video seems to be giving a cheeky wink to fans, with the group saying their differences are behind them. It's a nice touch.
