Today (October 9th) marks what would have been John Lennon's 72nd birthday. By nightfall tonight, hundreds of fans will have made the pilgrimage to Central Park's Strawberry Fields in New York City for a day of remembrance, sing-alongs, and celebrations dedicated to the memory of Lennon. Strawberry Fields, a triangular patch of land dedicated to Lennon by the city of New York and named after the Beatles' 1967 hit, sits directly across the street from the Dakota, Lennon's Manhattan apartment building, where he was gunned down on December 8th, 1980 at the age 40. Today is also Lennon and Yoko Ono's son Sean Lennon's 37th birthday.
