Celebrate Canada Day on Tuesday.
Company
The news last year was that Broadway's Stephen Sondheim was working on a rethink of his 1970 musical that would cast the protagonist (a bachelor named Bobby) as a gay man. Alas, while the sexual-identity switcheroo would be a sweet fit for Toronto's WorldPride schedule of happenings, Theatre 20's current production of Company will play it straight, with Dan Chameroy playing a single man whose life is judged by married friends as incomplete without the company of a wife – perhaps the hip, earthy Marta, portrayed here by cabaret-songstress Sarah Slean. To July 13. $30 to $69. Berkeley Street Theatre Downstairs, 26 Berkeley St., 416-368-3110 or canadianstage.com.
Michael Bublé
"He charmed the joint." That's what The Globe's Marsha Lederman wrote about crooner Michael Bublé's recent homecoming at Vancouver's Rogers Arena. This weekend, at ACC, expect more of the same: charisma, shenanigans, upbeat pop moments and generous sentimentality. The aw-shucks star will razzle and dazzle and hustle his heart out – at your service, total commitment. He may not have achieved his boyhood dream of becoming an NHLer, but there's no smoother skater alive. June 28 and 29, 8 p.m. $66 to $136. Air Canada Centre, 50 Bay St., 1-855-985-5000 or ticketmaster.ca.
Canada Day Extravaganza
On Monday evening, just after you catch the sundown creeping 'round your back stairs, head to Harbourfront Centre for a two-barge, 20-minute firework outburst, synchronized to music. The event is part of a five-day stretch of music, dance, film and family diversions. Other Canada Day celebrations happen at Mel Lastman Square (5 to 10:30 p.m.) and Woodbine Park (live classic rock all day). And speaking of Sundown, musicians Tom Wilson, Ron Sexsmith and others will celebrate Gordon Lightfoot's memorable 1974 song and album on June 29 at Harbourfront (8:30 p.m., free). June 27 to July 1. Free. 235 Queens Quay W., 416-973-4000 or harbourfrontcentre.com.
The Science of Rock 'n' Roll
Think all you need for rock 'n' roll are three chords? Think again, Elvis. A new interactive demonstration not only explains the technology behind the music, but also explores the physiological effects of rock music on the listener. (There's more to it than the old Maxell tapes poster with the stereo speakers and the dude with the windblown hair would indicate.) Curated by music broadcaster and aficionado Alan Cross, the exposition gives lessons on rock history and musical theory, with a focus on how science has shaped popular music. Open daily, 10 to 4 p.m. (10 a.m. to 5 p.m., weekend and holidays). $13 to $22. Ontario Science Centre, 77 Don Mills Rd., 416-696-1000 or ontariosciencecentre.ca.
Toronto Jazz Festival
Closing down this year's sprawling jazz affair is the self-motivated guitarist Bill Frisell. His current project is "Guitar in the Space Age," which involves the six-string maestro's idiosyncratic exploration of American music in the 1950s and '60s. Mr. Frisell's musical inspirations were adventurers such as Speedy West, Brian Wilson and Dick Dale, artists whose inventions will be represented here. Only the sky was the limit for them, as it still is today for Mr. Frisell, an artist who continues to elude encapsulation. June 28, 8 p.m. $52.50. Jane Mallett Theatre, 27 Front St. E., 1-800-708-6754; more show listings at torontojazz.com.
