EdgarBlythe probably gets it about right. I think it notable that song lyricists are (apparently) not considered to be writing poetry.
In the clearing stands the boxer, and a fighter by his trade.
And he carries a reminder of every glove that laid him down...
or cut him till he cried out in his anger and his shame
"I am leaving! I am leaving" but the fighter still remains.
