3. David Walliams talks to us about his book and
audiobook Gangsta Granny which published on
October 27, 2011. This interview also talks about
David's challenge for Sports Relief. It was recorded on
September 6, 2012, the day after David took on 140
miles of the unpredictable and very dangerous river
Thames in order to raise money for street children in
Kesumu, Kenya.
