Liverpool's mayor, Dorothy Gavin, led Lennon devotees who laid wreaths at the foot of a bronze statue of The Beatles in the city's Cavern Walks shopping center. The center was built on the original site of the Cavern Club, made famous when The Beatles played there in the 1960s, and has become a place of pilgrimage. ``Give peace a chance,'' the title of one of singer-songwriter Lennon's greatest hits, was the theme for the day. … Lennon and his wife, Yoko Ono, were returning to their apartment in New York's Dakota apartment building after a recording session on Dec. 8, 1980, when Lennon was shot to death by Mark David Chapman, a deranged fan to whom Lennon had given his autograph only hours before. Lennon was 40. A spokesman for the Lennon family said Ms. Ono and the couple's son, Sean, were in Europe and would spend the anniversary privately. … Peebles said late in 1980 that Lennon had just recovered from a period when he had ``gone off the rails'' and his relationship with Ms. Ono had suffered. ``But (when I saw him) they'd had the baby, Sean had been born, and everything was great.''
