The success of the Sugababes is not only well-deserved, but impressive.

Pop groups tend not to have much longevity and we've become accustomed to the ever familiar flash-in-the pan syndrome.

We've learned to digest our favourite pop acts by savouring them for as long as they'll last, then praying they'll reunite ten years down the line. We know full well that today's 'hot' may well transpire into tomorrow's 'not'.

The Sugababes, thankfully, are an exception to this. They have achieved ten years of success having sold out international tours and received dozens of awards, not to mention scoring more Top 10 hits with original songs than any other girl band since Sixties super-trio, the Supremes.

From Push The Button and Hole In The Head, to Round Round and Ugly, Sugababes have sold more than two million singles, hitting the No 1 slot four times.

They've sold more than five million albums (including three triple-platinum discs in the UK) and they're also the first girl group since the 1980s to release more than three hit albums, trouncing Destiny's Child and the Spice Girls.

The trio has become synonymous with imaginative, cutting edge, effervescent pop music, turning in some defining moments and picking up countless plaudits including two Brit awards, and a Q award.

And, much like the Supremes, there's no doubt that the warm, harmonic, sophisticated sound of the Sugababes will go from strength to strength, with the latest line-up of the group proving to be a dynamite combination.

Keisha Buchanan, Heidi Range and Amelle Berrabah look set to stick around.

The girls are down-to-earth and passionate about their music, and are particularly excited about the 29-date UK tour they're about to embark on, which rolls into Bradford later this month.

"I'm really excited about getting out there and seeing the fans again and seeing how they react to the new material, " says Keisha. "We can't wait to see the fans who have stuck with us throughout everything. Touring is like a way of us saying thank you."

With the success of Change, the band's sixth studio album, and the first album to feature vocals from newest band member Amelle, they certainly have something to celebrate.

The Sugababes have worked hard to push the boat out with this tour by injecting as much creativity as they can into their performances, which includes more daring outfits than ever before.

Heidi says: "They're a little bit more dramatic than we've had before. They're in more of a 'stage' style. We had such a brilliant time when we were filming the Denial video and trying on all the different costumes so that inspired us.

We wanted to try something a bit more directional and there's a disco-ball inspired outfit, which I'm excited about."

Intent on enjoying every second of their time on the road, these twentysomethings plan to give it their all and enjoy themselves, both on and off stage.

"We had such a good time last year everywhere we went. We got to see loads of new places and go to some great bars. We had so much fun.

"The parties are a bonus to touring. Everyone's on such a high and having such a brilliant time" says Amelle.

They're eager to go, have some risqué outfits waiting in the wardrobe, and new dance routines and vocal acrobatics at the ready.

That said, it's often the unpredictable elements that are planted firmly in the girl's memories after a tour, as Keisha recalls.

"I remember on the last tour we were doing Walk This Way and Heidi didn't get ready in time so she didn't come out until the chorus so I had to sing all her words! Luckily our fans are really forgiving when things go wrong.

They're great."

Sugababes are at St George's Hall on Monday March 31. For tickets ring (01274) 432000.
