In the scene where the three guys are driving in the orange truck, just before the motorcycle cop pulls them over, there is a song playing. It goes: "Canada, A-AH....Canada A-AH, Canada A-AH, Canada A-AH....CAN-A-DA CAN-A-DA..."

Can anyone help me?

The song I am looking for is here: http://www.youtube.com/watch?v=6tdZkcV8o54
