George Takei in the musical ‘Allegiance’: Your quarantine must-watch of the day

Long before he was Mr. Sulu on “Star Trek� or the social media star that he is today, George Takei was a Japanese American kid growing up here in California.

Then came World War II, when Takei, his family and tens of thousands of other Americans of Japanese ancestry were stripped of their rights by the U.S. government and forced into internment camps. A lifetime later, Takei’s childhood experiences served as inspiration for the historical musical “Allegiance.�

Broadway on Demand will stream a performance from the show’s 2015 Broadway run, headlined by Takei and Tony winner Lea Salonga (“Miss Saigon�). The event starts at 4:30 p.m. Friday with a virtual red carpet featuring the cast and creative team, followed by the premiere at 5 p.m. Both can be streamed for 48 hours for $14.99 at broadwayondemand.com. The production, minus the preshow, will be available on demand thereafter for $8.99.
