The David Tennant Treat 4 Today is a MP3 from when David Tennant was filming Broadchurch.
It was during Chris Moyles final week on Radio One. David rang in and they had to guess who he was!
The beginning part of this clip talks about watching but this is the MP3 (it was on the radio!)
Keep listening after David Tennant stops talking too as they say some lovely things about him!
Click here to listen to the MP3 and don't forget to watch Broadchurch on ITV tonight at 9pm!
