DEAR JOHN: On the eve of the 28th anniversary of John Lennon's death, a dozen local musicmakers converge on the Central Park Naumberg Bandshell for New Arts NYC's marathon concert "For the Love of Lennon." Expect John covers galore. 1PM.
D.I.Y. NOT: The Handmade Holiday Craft Fair taking over Bushwick's 3rd Ward promises more than 50 vendors of gifty goodness, including "a butcher, some bakers and maybe even a candlestick maker." Can't argue with that. 12PM-7PM.
LET THERE BE LIGHT: How serious is the wattage behind the 12th annual lighting celebration of Central Park's Charles A. Dana Discovery Center at 110th Street? The event is actually sponsored by Con Edison. 3PM-5PM.
NPRU KIDDING?: Hey, you know Garrison Keillor? Of public radio's Prairie Home Companion fame? He's making his cabaret debit tonight at Feinstein's with a show titled "Man in Tux in Red Shoes in Piano." Something tells us this ain't your mama's cabaret. 8:30PM.
And don't forget to check out Brooklyn Flea's Gifted Market, which runs every Sunday 'til Christmas.
