Killer lead vocal. I'd go get the volume automation out and drop the guitar riffing down in volume just a hair when the vocals are doing their thing, particularly at 1:40. When the guitar is sparse and trading with the vocal, it totally works.
Great tune and I liked the second mix very much! Prolly if Peter Gabriel was fronting Pink Floyd, that would sell a lot of tickets back in the day.
cheers,
