Yoko Ono has urged Beatles fans to recreate her and late husband John Lennon's "Bed-In for Peace" - 40 years after the famous stunt.
The couple stayed under the covers for days on end at hotels in Amsterdam, Holland, and Montreal, Canada in 1969 to promote their campaign for world harmony and the end of the Vietnam war.
And the Imagine hitmaker's widow is asking fans to mark the 40th anniversary of the event by staging similar peaceful protests.
Writing on her website, Ono says, "This year, 2009, is the 40th anniversary of the Bed-In. If youre planning a tribute Bed-In of your own this year, tell us about it in the comments below, and/or send pictures and stories."
