Making plans? Short on ideas? No worries. See June Wulff and Courtney Hollands' picks for the top things to do around the Hub this weekend. Take a peek, then get out!
Disco Bar Crawl: What are you doing Friday night? Cancel your plans and head to Harvard Square for this glittery, bacchanalian night o' drinking and dancing. The crawl — featuring special disco cocktails, like the "Puck's Pantydropper" — kicks off at Upstairs on the Square and then stops at OM and the Russell House Tavern before landing at Oberon for the funky-fabulous "Donkey Show." 6 p.m. (The show starts at 7:30 p.m.) Harvard Square. $55. 617-547-8300. americanrepertorytheater.org
John Mayer: A Rolling Stone review described this crooner's "Battle Studies" as "terrific when Mayer drops the seriousness, pondering, and sending up his reputation as a rake. On 'Half of My Heart,' with Taylor Swift, Mayer plays the dude who kisses with one eye open, scanning for his next conquest." Do you agree, or do you prefer the solemnity of "Heartbreak Warfare" and other tracks on the Grammy winner's latest record? Train opens for the blues guitarist and pop/rock singer, songwriter, and Aniston ex. 7 p.m. $30-$72, $99 four-pack special. Comcast Center, 885 S. Main St., Mansfield. 800-745-3000. livenation.com
'All About Eve': "Fasten your seat belts. It's going to be a bumpy night." Gee, we didn't know they had seatbelts in 1951 when Bette Davis and Anne Baxter starred in this Hollywood classic. Enjoy it at "Movies by Moonlight," but don't get so caught up in the drama about backstage backstabbing that you forget to take in the view of Boston Harbor. "Tootsie" is up next on Aug. 13. Dusk, weather permitting (Through Sept. 3; movies are subject to change). Free. Boston Harbor Hotel, Rowes Wharf Sea Grille harborside terrace, Rowes Wharf. 617-439-7000. bhh.com
Rock & Roll Yard Sale: We would never part with our Connie Francis or Beatles vinyl, and if you're a collector, too, track down some gems at this sale Saturday. About 50 vendors will set up in Union Square to peddle vinyl records, concert posters, and other music-related stuff, vintage clothing, crafts, and art. Live music will be by The 'Mericans, Sleepyhead, Thea Hopkins, and more. 3-7 p.m. (rain date Aug. 8). Free. Union Square Plaza, Somerville. somervilleartscouncil.org
Urban Music Festival: What used to be the Peace Hip-Hop Festival is now the Boston Urban Music Festival, and City Hall Plaza is where you'll find all this urban music in the form of hip-hop, R&B, soul, and pop. Starting duties go to Lynn lyricist M-Dot who recently won the title of Best Hip-Hop Artist in the WFNX Boston 2010 Best Music Poll. Other forces to be reckoned with are Pittsburgh rapper Wiz Khalifa, former Harvard student Ryan Leslie, and Bad Rabbits. 3-7 p.m., rain or shine. Free. City Hall Plaza, Government Center, Boston. 617-635-3911. cityofboston.gov/arts
Blueberry Festival: Visit the Jam Kitchen to see folks make old-fashioned blueberry jam, and don't miss out on a homemade blueberry dessert. Stroll the paths of the wildflower garden, walk the wooded trails at the Old Briar Patch, see the resident animals, watch the Cape Cod Woodturners, and check out gallery exhibits. 11 a.m.-2 p.m. $4 blueberry dessert. The Green Briar Nature Center, 6 Discovery Hill Road, East Sandwich. 508-888-6870. thorntonburgess.org
Rihanna: According to imdb.com, this star's nicknames have included RiRi, Caribbean Queen, the Barbados Babe, the Alien Princess, and...Thunder Thighs. Perhaps this last one was the inspiration for "Rude Boy." At the geriatric age of 22, the 5-foot-ten singer was only 16 when she met Jay-Z and signed on to his Def Jam Records label. The Grammy-winning singer's latest release is "Rated R," and her Last Girl on Earth Tour welcomes special guest, Ke$ha. 7:30 p.m. $24.75-$99.75. Comcast Center, 885 S. Main St., Mansfield. 800-745-3000. livenation.com
Food Truck Festival: Man, why doesn't Boston have a food truck scene like [insert name of city here, probably New York or Los Angeles]? Hold your horses and bring your appetites, friends: Citysearch is hosting the first annual Food Truck Festival at SoWa Market (thanks in part to a micro-grant from Feast). Speed's Hot Dogs, M&M Ribs, Cupcakory, South End Pita, and Grillo's Pickles are just a few of the vendors that will be at Sunday's chowdown. 10 a.m.-4 p.m. 500 Harrison Ave., Boston. boston.citysearch.com
Singles Canoe/Kayak Paddle: Sick of online dating sites? Why not venture out into the world and into the water for this event? We can't guarantee you'll meet Mr. or Ms. Right, but you'll get a good workout on James Pond and maybe a new canoe or kayak buddy. The South Shore Natural Science Center asks that you bring your own boat, paddles, and life jacket. And how about bringing your spirit of adventure. Have fun. 1-3 p.m., rain or shine. Free. Adults only. Meet at South Shore Natural Science Center, 48 Jacobs Lane, Norwell. 781-659-2559. ssnsc.org
Parkland Games: Let the games begin. After hours of badminton, bocce, volleyball, croquet, and other games, you might need the one-hour yoga session. Did we mention Sunday's folk dancing (also Aug. 15)? The Charles River Conservancy and the Department of Conservation and Recreation bring you these games along the water's edge (no, swimming isn't one of the activities). 2-6 p.m., weather permitting (Sundays through Sept. 19; yoga through Sept. 5 from 5-6 p.m.). All ages. Free. Upriver from the Weeks Footbridge on the Charles River, off Memorial Drive, Cambridge. thecharles.org
