You're about to listen to a BBC podcast, but this is about something else you might enjoy.

My name's Katie Lecky and I'm an assistant commissioner for on demand music on BBC Sounds.

The BBC has an incredible musical heritage and culture and as a music lover, I love being part of that.

With music on sounds, we offer collections and mixes for everything, from workouts to

helping you nod off, boogie in your kitchen, or even just a moment of calm. And they're all

put together by people who know their stuff. So if you want some expertly curated music in your life,

check out BBC Sounds. Hello, I'm Krista Young.. Thank you for downloading this podcast of Desert Island Discs from BBC Radio 4.

For rights reasons, the music choices are shorter than in the radio broadcast.

My castaway this week is David Tennant. His brilliance in portraying Doctor Who has defined the time lord for a generation of children, and indeed redefined it for parents, who up until he took over, had thought the only real Doctor Who was in possession of a mop of curls and a long stripy scarf. Rayfish, dynamic,

solitary and daring. His Saturday evening intergalactic adventures have secured BBC One blockbusting figures and the actor himself, the sort of household name status normally reserved for premiership

footballers and rock stars. Yet, despite being voted the best Doctor Who of all time,

he says, I always have that Presbyterian voice in my head saying,

could do better.

But he admits, I quite like that.

You don't give interviews very often, I don't think, David Tennant.

I do a lot of interviews, but I tend to stick to the lighthearted frothy stuff.

I don't do many interviews like this often, no.

Okay.

And that is just to try to preserve a part of you that's not the doctor and it's not out there all the time.

I think so, yes.

Okay.
