Apparently Heavenly records are holding a festival featuring all their old artists- does anyone know the line-up?

I've copied this from an email but that's all I know:

FOREVER HEAVENLY
Friday 12 - 14 September 2008

A weekend festival celebrating 18 years in the life of the Heavenly Recordings label. ounded in 1990, Heavenly has been home to artists from Saint Etienne and Manic Street Preachers through to Beth Orton, Doves, The Magic Numbers and Edwyn Collins. Now upon reaching some kind of adulthood, the Heavenly label has decided it's time to have a party.

For three nights, they take over Royal Festival Hall, Queen Elizabeth Hall and the Purcell Room, bringing back the great and good from the label's entire history, and putting on the best urban festival line-up of the summer. Expect stadium-sized special guests alongside acoustic troubadours, the odd Sunday Social stalwart and those who are just Forever Heavenly.
