As the PLASTIC LENNON BAND's Myspace page plainly states, the group "celebrates the life and music of the late great John Lennon." Which isn't such a bad idea; if you're going to ham out on anyone's tunes, it might as well be a Beatle's. The lineup features members of local acts Outformation and the Last Waltz Ensemble paying homage to the fallen peacemonger with a set of later Beatles numbers and Lennon's solo work. $8-$10. 8 p.m. Smith's Olde Bar, 1578 Piedmont Ave. 404-875-1522. www.smithsoldebar.com.
