There was a time many years ago when I fanatically collected Genesis bootlegs, but this early gem never showed up on any of them. “The Light” was reportedly a staple of the band’s live shows circa 1970-1971, but they evidently never recorded a studio version of it. Small parts of the music were later incorporated into “Lilywhite Lilith” and “The Colony of Slippermen” from The Lamb Lies Down on Broadway.
This 1971 recording from La Ferme in Woluwe-St Lambert, Belgium, is the only known recording of the song anywhere, ever….
