Yoko Ono attends the world opening of 'Imagine Peace' at Montreal Museum of Fine Arts. Montreal, Canada - 31.03.09

The Lundy's Lane Historical Museum in Ontario, Canada is setting up an exhibit in tribute to the Beatle and his bride's post-wedding stop to the site on 1 June, 40 years ago.

And to show her gratitude, Lennon's widow has donated never-before-seen footage of their Niagara Falls trip, immortalised in Lennon's video for Stand By Me, to the city's council.

The newlyweds made history on their honeymooon with their famous "bed-in" in Montreal's Queen Elizabeth Hotel, in which they spent a week wrapped up in sheets to protest the Vietnam war.
