Its great fun to have the other ghosts to play off, because we are different personalities.

You get a script and you sit at home wading through it, to be honest, because you're trying to make sense of it and the stage directions and so on.

It's only at the read through, the first day we all meet, all a little nervous, [that] it comes together. Somebody jumps in and wham! you're off. Suddenly it's fun and suddenly that page does make sense and your lines make more sense.

You see us in the studio and we're all just falling about with laughter at each other, at ourselves. There's something about radio that's really relaxing. Nobody gets a close-up, there's no drama. You just lean into the mic, it's you, somebody else leans in, there's nobody saying, 'Here is my close-up Mr DeMille,' and therefore it's relaxing and a riot.
