It's a suitably thrilling way to close the record and I'm willing to bet serious money that Guided Missile wish they'd put it out on 7". That said, The Mor Paranoids' cover of the aforementioned Swell Maps' "International Rescue" is also a real contender:
"Circular" was released in an edition of 100 copies on the best format yet devised by mankind: 10" vinyl. According to the Where It's Is Where You Are (they've had a great year, haven't they?) bandcamp page there are only 15 copies left - nudge, nudge. There's no way on earth that "Circular" won't make my 2014 Top 10.
(Big thanks to Paul E for buying "Circular" on my behalf after none of the local record shops stocked it.)
