Into the Wardrobe

Does anyone know if the original recording (or, indeed, any recording) of this play cycle by Dorthy Sayers is available?

I've never been able to find one. I'd like to have one, myself. I've always wanted to do Pilate's wife's dream (Sequence 6 of play 11, 'The King of Sorrows') as part of an Easter pageant, and it would be help to have a recording of the background voices reciting the Creed.

I think about a million years ago my local public library had it on an LP. They don't have LPs anymore.
