Gary Morecambe, 58, an author from London, said the family were “genuinely excited” about the auction of their parents’ lifelong possessions.
He said seeing the memorabilia go to new homes marked a definitive end of a wonderful era that “for Gail and I at least, began in the 1950s”.
“I think what makes it such a unique occasion, and such a momentous time in our lives, is that our mother barely touched anything in the house after our father’s death.
“Hence we have had everything quite literally under the same roof for 56 years.
“When thinking about my father, it’s always easy to contemplate the great comedian he unquestionably was to the detriment of the other side of his life – the home-loving man, who had a serious passion for the natural world.”
Ms Stuart, 71, added that while growing up she had no idea her childhood was blessed with the material surroundings and “special individuals…our parents”.
“Both had great gifts, both made their lives about family, both were always kind, humble, honest. Both received an OBE. All my memories are in glorious Technicolor.
“We grew up sharing Dad with the British people, the amazing fans. It wasn’t until Dad died that I realised the affection for Dad and for Morecambe and Wise ran so deep.”
