'Hedwig' box office takes huge drop after Harris exits

As expected, the weekly box office grosses for "Hedwig and the Angry Inch" took a nosedive last week, with the show taking in $648,738 during Andrew Rannells' first week playing Hedwig, compared to $1,139,903 the week before, when Neil Patrick Harris was still playing the transgender rock star. All things considered, the current gross is still pretty good, especially since there are only seven performances a week, as opposed to the norm of eight, and the theater was still filled to almost 90% capacity.
