It is never a good sign when players from both teams are physically shaking with laughter during the performance. However, "singer" Measha Brueggergosman, seemed unaware of the affect her performance had as she posted the following message on her website afterwards.
"Just finished singing the American & Canadian Anthems at the Senators/Penguins game in Ottawa. WHAT A RUSH!"
Yes,there is nothing like the rush of public humilation.
