The selfless married father-of-one comedian, 43, has already raised over £148,000 with two events for desperately ill fan 37 year-old Polly Haydock.
Now the Phoenix Nights star will incredibly once again lend his support by doing a third fund-raising event at Blackpool Opera House, in Lancashire, this Sunday, June 4th.
The award-winning comedian will offer secret insights into his shows – including never seen before outtakes.

Mrs Haydock's delighted husband Dan said: “Peter rang us about a week ago and asked how Polly was and said he was going to do another show for us.”
It is hoped the new event will prove to be just as successful as last year’s shows and give another huge boost to Polly’s fund-raising.
Mr Haydock, of Gadbury Fold, in Atherton, Lancs, said: “We are so grateful that Peter is still supporting Polly.

“It means we can get her back to Germany quicker and hopefully get her back on her feet.”
Mrs Haydock was diagnosed with bowel cancer in October 2015.
But last July she was given the bombshell news that she had six months to live, after the cancer spread into her lymph nodes, bones, liver and lungs.
Doctors said her life could possibly be prolonged by chemotherapy, but it would probably not be a cure.
Mrs Haydock refused to accept the devastating news and learned about immunotherapy after researching alternative treatments.
So instead she launched an appeal to go to Germany’s Hallwang Clinic for immunotherapy, which she believes gives a better chance of survival.

It boosts the body’s natural defences to fight off cancer, by using substances either made by the body or in a laboratory to improve or restore immune system function.
Last November Mrs Haydock had the first three-week course of immunotherapy at the Hallwang Clinic before returning to the UK to spend Christmas with her family.
Afterwards she said there are signs that the treatment was having the desired effect – but she still needs more courses.
She said at the time: “The treatment was very harsh and I really did struggle, but the good news is that it looks/feels like something is working.
“Although it is very early days my tumour pain has eased considerably and I am taking that as a positive.
“I am hoping and praying that the tumours have started to shrink.”

Her story touched the hearts of people around the country, who heard about her plight and gave donations.
A GoFundMe page with a £410,000 target for the revolutionary, potentially life-saving treatment has now passed the £222,000 mark.
She is currently a patient at The Christie hospital in Manchester and wants to return to Germany as soon as possible, as that treatment is not available in the UK.
