Lyric discussion by godnose 

It seemed to me to be about a girl he knew from when he was younger. Living in the lower classes, but she "made it out" and he's "still stuck here". He is now spying on the person, and the others now in the upper class "lords and ladies" he's going to take them on. These ideas of "different class" are shown in the homonyms parks, grass, birds. In his world these things mean different things. The describing her as having Ladbroke Grove looks is puzzling. Perhaps he is talking about her in the past before she found her elevated status, he was turned on by her grimey look before. Instead of "sing" I think it's saying "sink", - "let's sink again" go back to our lower class status, to "take her from this sickness, dinner parties and champagne" -both relics of upperclass wealth. The "sleeping with your wife" bit, he is talking to the girls husband I think. Great song.
