'I Is Someone Else'
By Luc Sante
Michael Gray, who is probably Dylan's single most assiduous critic, turns up a quatrain by Robert Browning that the mind's ear has no trouble hearing in Dylan's voice, and not only because the end rhymes prefigure "Subterranean Homesick Blues":
Look, two and two go the priests, then the monks with cowls and sandals
And the penitents dressed in white shirts, a-holding the yellow candles
One, he carries a flag up straight, and another a cross with handles,
And the Duke's guard brings up the rear, for the better prevention of scandals.
Dylan himself, in the Songwriters interview, cites a Byron couplet that is equally convincing: "What is it you buy so dear/With your pain and with your fear?" But then, as he told Robert Hilburn of the Los Angeles Times,
It's like a ghost is writing [the] song.... It gives you the song and it goes away.... You don't know what it means. Except the ghost picked me to write the song.
