I want to know the answer to the following question:
Who wrote the comedy sketch for the cast and crew?
All the background I'm provided with is that "On 13 March 2015, several members of the cast and crew, including Craig, Whishaw, Wilson and Mendes, as well as previous James Bond actor, Sir Roger Moore, appeared in a sketch written by David Walliams and the Dawson Brothers for Comic Relief's Red Nose Day on BBC One.". Is that enough to answer the question?
Answer: yes
