Can you help please? john bishop tickets???!?

My best friends birthday is on the 25th July, and we both LOVE John Bishop (the scouse comedian). I was wondering if anybody knows if there is any tickets I can buy for around that date? Either one of his tours or even for his program 'John Bishops Britain'. I've looked everywhere but can't find any! I really hope I can get them, it would be the perfect present for her. xx
