Join a massive line-up of the biggest names on the Fringe for a raucous evening of comedy to help the fight against brain tumours. Brain tumours are the biggest cancer killer for children and adults under 40 and increased funding for research is desperately needed. Box office proceeds will go straight to The Brain Tumour Charity, and Underbelly will match this amount as a donation to the charity, doubling the amount that we can raise on the night. Check underbellyedinburgh.co.uk for line-up.
