What's the name of that song

Hey!
I heard a song which I really liked, but I can't find out how the song is called or who's the artist.
It's a very "happy" song, ska-like, and in the chorus the sing "I've got one shot left, in the chamber.....12 steps left on the ...ramp"
at the beginning of the song he is more saying than singing that he's got one foot in the grave and the other's kicking a bucket.
Hope you can help me, that song is stuck in my head and I need it
cheers
