From Ananova:

Ant and Dec will try to retain the Music Industry Soccer Six title this year. Other celebrities taking part include Nick Moran, Dean Gaffney, Michael Greco, Gary Lucy, Ralf Little, Lisa Rogers, former Steps star Lee Latchford Evans and Hear’say’s Suzanne Shaw. The football tournament will be held at Chelsea FC’s Stamford Bridge ground on May 26. Last year over 15,000 fans saw Ant and Dec’s team narrowly triumph over Rod Stewart’s outfit. Robbie Williams is yet to confirm whether he will be assembling a team this year to reclaim the crown they took in 2000. A portion of the proceeds from each ticket sale will be donated to Help a London Child and The Samaritans. Tickets are available from Ananova’s ecommerce partner First Call.

According to Truth or Tat on Channel 4, a spokesperson says that H & Claire and Faye’s singles still might clash and be out the same day.

Thanks to Donnie for this information:
The song Over You, due out on H & Claire’s single, has the credits of A Frampton / T Momrelle – we’re not sure if this is the same song but it could well be.
