Gavin and Stacey star Ruth Jones and West End talent Ruthie Henshall are among the line up announced at Ipswich's Regent Theatre this December.
Comedians Dave Baddiel and Joe Pasquale join the line up for this year's 'Happy Christmas' show on Monday December 9.
The show, run by East Anglia's Children's Hospices and spearheaded by celebrity patron Griff Rhys Jones, aims to fundraise for the charity.
Jones plays the serious but unpredictable Nessa in Gavin and Stacey, which has just wrapped up filming for the Christmas special.
Henshall, daughter of a previous editor of this newspaper David Henshall, has appeared in Cats, Chicago, Billy Elliot and Les Miserables on the West End.
Rhys Jones said: “We’re thrilled and excited to be celebrating the fifth anniversary of our Ipswich event, as well as now going out all over the region, hosting simultaneous shows in Cambridge and Norwich.
“It’s going to be a bumper night of festive merriment, with many more names to be confirmed soon. Watch this space!
“Tickets are already selling fast, so get in quick. It’s a way of giving a small Christmas present to an incredible charity - a vital service that is largely paid for by the people of East Anglia.
“EACH does such important and heartbreaking work, so please join us if you can. I look forward to seeing you there.”
More than 800 tickets for the show have already sold and can be booked online.
