What would John Lennon think of the war in Iraq, if he were alive today? Well, it's not hard to imagine -- the writer of the anti-war anthem "Give Peace A Chance" would have opposed the current conflict in the Middle East, says his widow, Yoko Ono.

"I'm sure John would have been terribly upset," Ono told the BBC this week from Liverpool, England, where her late husband's childhood home is being opened to the public. "And I'm sure that he would have expressed his anger and told them off," she said, referring to British Prime Minister Tony Blair and President George W. Bush, about "how stupid it is to go through this."

Ono, who participated in "bed-in" vigils with her husband in the 1960s to protest America's part in the Vietnam conflict, added: "As Gandhi said, 'An eye for an eye will make us all blind,'" according to the BBC.

Meanwhile, on the first night of his European tour in France on Tuesday, former Beatle Sir Paul McCartney seemed to be channeling the spirit of his former songwriting partner.

McCartney had just finished performing the song "Here Today," a tune he penned in the wake of Lennon's 1980 murder, when the crowd of 15,000 at the Bercy Sports Centre in Paris spontaneously broke into the chorus of "Give Peace A Chance," reports the Associated Press. McCartney, who was visibly surprised, according to AP, joined in with the unscheduled sing-a-long, but made no further comment about the war.
