As you may or may not know, Genesis was not Phil's first band. That honour would belong to Hickory (later renamed Flaming Youth). They did a song, you know? It was called Green Light. Would you like to hear it? Oh, okay then: Green Light
Did you like that? I expect you'd like to hear another. Check this out: Lying Crying Dying
I particularly like that last tune. At times, you can hear the influence of Cream in Phil's singing. Pretty hip.
