The `Big Yin' has been a stern critic of "patriotism" throughout his career, ridiculing Scottish nationalists both on and off stage.
But as the Brexit vote divides British voters, he has spoken out for a pan-European togetherness which could see Scotland leave the UK.
"One thing I've never had any interest in is hating England and the English," according to excerpts from the book in today's Sunday Times.
"I like Thomas Hardy as much as I like Robert Burns. As an anglophile, I've never shouted for Scottish independence - but I might be changing my mind now."
But his new book adds: "The Brexit vote is a disaster and the breaking up of togetherness of Europe is a crime bordering on a sin. I think the more are together, not separate the happier they will be.
"The most important thing for Scotland is to keep our contact with Europe. Scots voted to stay in Europe and if the only way for us to do that is to become independent from England, that may just be the way to go. And I never thought I would say that."
