STAGE

Thursday night’s performance of “Cabaret” at London’s Strand Theatre went on with music again, marking the second straight night the musical has been staged without an orchestra. That day, the musicians were on the sidewalk picketing the allegedly illegal firings of five musicians. “We have a musical without any music, but the singing is wonderful, and it is in the tradition of English theater,” producer Willie Hancock told the audience of 51, who dotted the 897-seat playhouse in London’s commercial West End theater district. “It’s great,” said Joe McCormack of San Francisco, who was in the audience. “I’m a physician. Music damages your ears.”
