An improvised Gavin & Stacey musical from James Corden and Ruth Jones

It’s from Ruth Jones’s forthcoming show, Ruth Jones’s Christmas Cracker, and sees James Corden and Ruth Jones improvising a song in character for a potential Gavin & Stacey musical.

What do you think? Would you like to see that musical? Joanna Page has form, as does Rob Brydon, but can the rest of the cast sing?
