Under a Killing Moon Easter Egg - Piano Lessons

When you get to the day when Tex needs to get inside the Golden Gate Hotel to get incriminating evidence on Sal, look around the large condo for a little bit. In one room is a large grand piano. If you have Tex look at it he says, "A LARSON grand piano, that's better than a Staufway." The game The Seventh Guest had also been released around the same time. I understand this is a joke the creators put in to say that Under a Killing Moon was better than 7th Guest. I agree, apparently so did many others, because Killing Moon ended up selling a lot more.
