Beatles marathon

New York-based Beatles tribute band Beatles for Rent will get by with just a little help from its friends this Sunday as the band's 10 members attempt a performance of 162 Beatles songs in one day -- with no breaks. So "Come Together" and "Help!" them out with a cheering section at Greenpoint bar Coco66. Stay the whole time or come and go as you please. Can they do it? We think so, but it's sure to be "A Hard Day's Night." (Sunday, noon-midnight or later, FREE, Coco66, 66 Greenpoint Ave., Greenpoint, coco66.com, beatlesforrent.com)
