That just says everything about the NHL marketing team.
First some group of people had to decide that Melissa Etheridge would be a good idea to put up there in this game which is attempting to grab new viewers. Then this same bunch of brainiacs says, oh she wants to perform acoustic to a stadium full of people, that sounds like a great idea!
The last 10 homeless people with guitars I've seen were better than that and probably more relevant too.
They need to fire the entire marketing department for the NHL and bring in some new blood. What a joke.
