Here is the full expanded "Better Off Dead" which I originally got from the great Phelpster over at the "Manchester Morgue". If you are fan of this 80s comedy classic I recommend downloading this one. It has all the songs heard in the film right down to the songs Lane Meyer hears when flipping through the radio in his station wagon.
