The End Is Nigh lyrics

Don't you look outside your window It's cold outside It's cold outside People stare and you don't know It's cold outside It's cold outside You watch people come as they go It's cold outside It's cold outside Tally on and nowhere to go It's cold outside It's cold outside The end is nigh or so they reckon It's cold outside It's cold outside What's that flash on the horizon? I don't know I don't know
