Lyric discussion by mithgil 

The final words are a reference to a song by Noel Gay and Ralph Butler called "Run Rabbit Run". The lyrics go:

On the farm, every Friday On the farm, it's rabbit pie day. So, every Friday that ever comes along, I get up early and sing this little song

Run rabbit - run rabbit - Run! Run! Run! Run rabbit - run rabbit - Run! Run! Run! Bang! Bang! Bang! Bang! Goes the farmer's gun. Run, rabbit, run, rabbit, run.

Run rabbit - run rabbit - Run! Run! Run! Don't give the farmer his fun! Fun! Fun! He'll get by Without his rabbit pie So run rabbit - run rabbit - Run! Run! Run!

The words "I am no innocent son" always reminds me of the chorus to CCR's Fortunate Son, also. I don't know if that was intentional.

"How about rust, sullen leaves"

like the falling leaves are the color of rust
