Stumbled across a Genesis influence

Did Gabriel do that much research before writing that tune? Now that's taking the pop songwriting craft pretty pretty far. I highly doubt it, though. Not unless he studied ancient Greek and did a PhD in between changing costumes. Seems very plausible - make that highly probable - that a Keats poem was the primary source. But then what do I know... I've been studying medieval Arabic for 30 years so I can read the complete works of al-Abu Swahib in the original text, so that I can write a 4 minute pop tune. My musical career has been temporarily placed on hold (since the age of 13) till I'm ready to write that song. (After that, for my second song, I'm thinking of basing it on Bakhtin's theories of language, ideology and power. But first I'll have to learn Russian.)
