LONDON (AP) — Beatle John Lennon said here he plans to put up signs and billboards around the world with Christmas greetings and pleas for peace.

The pop musician said billboards would be erected in 11 cities saying: “War is Over. If You Want It. Happy Christmas from John and Yoko.”

Yoko is Lennon’s Japanese wife, who sings in Lennon’s Plastic Ono band and has appeared in the Beatle’s peace campaigns in a bed—in Toronto Montreal and Holland and inside a sack in London.

Lennon said the Christmas anti-war message would be displayed in London, New York, Toronto, Montreal, Amsterdam, Athens, Berlin, Los Angeles, Paris, Rome and Tokyo.
