Fairly simple chords, the timing in parts is slightly strange changing from off beat to 'on' beat, 
ending
is very ad lib but I'm pretty sure it's just G Am the same as the chorus (but I could be wrong) 
also the
lyrics are hard to hear clearly towards the end and I don't think the line 'you're going after 
crime' is 
actually what he sings (any ideas? answers on a postcard to..)
 Feel free to comment and rate.
