Originals: Memories by The Soft Machine (covered by Damon & Naomi)
Memories was a very early Soft Machine track from 1967, written by Hugh Hopper and recorded as a demo by Hopper, Robert Wyatt and Kevin Ayers by Yardbirds' producer Giorgio Gomelsky - that snippet of my knowledge was lifted from a cool article about early Soft Machine by Julian Cope.
Damon & Naomi covered the track for their first album More Sad Hits
Here's Damon & Naomi playing the track in a bookshop in 2008
Damon & Naomi's version includes the line "pet shops where people knew us", later it was pointed out to them that the lyric was actually "past shops where people knew us" although to my ears it still sounds like "pet" in the Soft Machine version.
