I saw Young Marble Giants back in February which inspired me to pre-empt this post, so this is pretty much a rehash of that - sorry!
Here's the original by the rather fantastic Young Marble Giants, recorded in 1980 and released on an EP on Rough Trade
Here's Dean singing it as released on Uncollected
Here's Naomi singing it as recorded for their 1990 Peel Session
Here's Young Marble Giants playing it at the above-mentioned gig in London in February
