Forty years after their breakup, the Beatles have proven that Beatlemania is far from over. Newly remastered albums have made their way up the sales charts, and their legacy has been immortalized in video-game form with the release of "The Beatles: Rock Band" earlier this month. The pandemonium continues at the Fox Theatre with RAIN: A TRIBUTE TO THE BEATLES, which boasts a repertoire of nearly 200 of the Fab Four's songs from their mop-topped "Ed Sullivan" days to the waning rooftop concert era. Through Oct. 11. $20-$67.50. Tues.-Fri., 8 p.m.; Sat., 2 and 8 p.m.; Sun., 1:30 and 7 p.m. 660 Peachtree St. 800-982-2787. www.ticketmaster.com.
