"Songs like Scandalous and One Night Stand have a lot of violins and cellos and strings," the girls told Newsround Showbiz. "So to hear them live will be just fantastic."
The Mis-Teeq girls have had plenty of practise playing live this summer, after performing at the V festival and Glastonbury, as well as loads of pop road shows.
But they admitted playing the huge festivals was pretty nerve-wracking.
"Sometimes we're very, very nervous behind stage thinking: 'Are people going to come and see us?'" the girls confessed. "But we got out there and it was packed and everybody was just having a really, really good time."
