The TV funnyman’s childhood home – the Centurion pub in Blackburn – was demolished after a fire in 2006 and the council have now approved an application to build 14 homes on the site.
Now Mack is hoping to secure a momento of his former home.
Speaking to the Lancashire Telegraph, he said: “I went back about six years ago and it was flattened completely.
“It would be nice to visit the site again before they do build on it. There was an old sign on the road at the entrance to the pub and I would love to trace it.
“If anyone knows where it is I would really like to buy it from them.”
Mack lived in the Centurion for three years from 1979, just after the pub was built.
He joked that with his father’s old house and his former school also demolished there would be nowhere left to put his blue plaque.
