Walk for Hunger

-- The 40th annual Walk for Hunger began today at 7:00, but will continue all day long. Participants will wind their way around through Boston, Brookline, Newton, Watertown, and Cambridge, on a 20 mile trek to raise money for Massachusetts food pantries and soup kitchens, an event made more pressing by rising food prices. Sponsored by Project Bread. Citywide, 7:00am-7:00pm. Donate something. More information.

Ring the Bells

-- The ringing of Lowell House Bells are as weird a Boston tradition as you are likely to find today. The bells in question came from a Danilov Monastery in Russia in 1930, and have marked time in Cambridge ever since. Today, spring will be heralded by a Russian bell concert and the annual performance of the 1812 Overture by the Last Minute Orchestra, a motley group of musicians, which performs the piece with only an hour practice. Kazoos and hydrogen balloons fill in the missing parts. Lowell House, Harvard University, 10 Holyoke Place, Cambridge, 1:00pm. Free, but admission for the bells performance is limited.

Opera

-- Louis Hector Berlioz, the best known French Romantic opera composer, finished Les Troyens in 1858, but never saw the masterpiece staged in its entirety. You can't really blame folks: the opera is really long. Based on The Aeneid, with a libretto by Berlioz himself, Les Troyens is traditionally performed in two parts. Today marks the end of Boston Symphony Orchestra's staging of the opera and the only day when it performs both parts. Symphony Hall, 3:00pm (part one) & 6:30pm (part two). $29-$103 each.

Buy an Awkward Date

-- No mate is more desirable than an improv comedian, and you will have the opportunity to pick among a gaggle of them tonight. ImprovBoston hosts a bachelor and bachelorette auction to raise funds for their new theater. Bostonist had the recent pleasure of grilling one of the dudes who will be on the auction block. Venu, 100 Warrenton St., 7:00pm. $7/$10.

Comedy

-- If ever you want to talk comedy in Boston, you gotta know a little about the Ding Ho, an old Inman Square saloon where local comedians banded together and launched themselves. Tonight, Ding Ho graduates are getting together as a benefit for comedian Bob Lazarus. The list includes Steven Wright, Lenny Clarke, Steve Sweeney, Barry Crimmins, Tony V, Kenny Rogerson, Chance Langton, Bill Braudis, Martin Olson, and Jimmy Tingle. Regent Theatre, Arlington, 7:00 pm. $45/$50. (CR)
