Three cyclists, David and his wife Pam Hart and Ian Williams will embark on the Knotty Ash Dash - a 60 mile ride between Wigan and Liverpool, organised in aid of Wigan and Leigh Hospice and St Mary's Church in Lowton.
And lending his support to the event is Knotty Ash funnyman, Ken Dodd.
The cyclists are hoping to raise thousands of pounds for the two causes and were promised that Dodd would give them directions to his diddymen's famous Jam Butty Mines.
Doddy said: "I fully back the hospice movement as it is very important. They are wonderful because they allow people to retain their dignity even when they are very very ill.
"It is a very brave thing to do to accept that you might not be around much longer. When I go out I think I want to go out with a bang.
"Getting caught in the act and being shot by a jealous husband at 150 years of age would suit me."
A five-minute photo shoot lasted a good hour and he even had time to sign numerous photographs for excited youngsters and their ecstatic parents.
The man did not stop for breath, and those around him could not help but hang on his every word - from hearing about his love of theatres, his disbelief that he has lasted this long, and how he recommends that all those who come to his never-ending stand up shows should bring some glucose tablets.
"An audience is a very special thing, and it takes a lot of hard work to take it with you. When I am doing my stand up I have to work with them, cajole them, treat them right. Those Leigh audiences are always up for a good gag.
"I have never done the same show twice it is impossible because every crowd is so different and you just learn to work with that."
After 56 years in showbusiness he is incredulous at the suggestion he might just want to stop and have a quiet life.
"I can't," he said, "I've gone on for this long why stop now? It's like asking a doctor or a nurse to just stop working, it's in my blood."
