Music: BGMC to sing for huge crowd

The Boston Gay Men's Chorus will sing for 500,000 people at a festival in Berlin on Saturday, executive director Steven Smith reports in his Euro tour blog. The crowd estimate was an eyeopener for chorus members who arrived Thursday; they've already been interviewed by German television. But clouds still loom over the group's performance in Wroclaw, Poland. Local right-wingers there are calling for the removal of the director of the Philharmonic Hall, where the BGMC will sing, Smith reports.
