TS: Tom Verlaine's "Kingdom Come" vs. David Bowie's "Kingdom Come"

btw, does anybody know if Bowie was, like, self-aware when he was recording his vocals? It sounds like he's got blood pouring out of both nostrils. Freddie Mercury with a horrible case of laryngitis, strung out on heaven's blow and hitting an all-time high note. It's so fascinating I'd probably prefer it to Verlaine's original. But is it a joke? The only recent thing that compares at all is those occasional moments on Rock'n'Roll (the climaxes of "Is This It" and "So Alive") where Ryan Adams voice gets unconscionably nagging or amateurish (which are probably the most fascinating moments on the album). But, fuck, that place that Adams visit for a couple seconds is where Bowie set up roost on "Kingdom Come." Any info on the creation of the track is very welcome.
