The US release of 'Piper' was a bit different than the UK release. Here are the track lists for both of them :
|See Emily Play||Astronomy Domine|
|Pow R. Toc H.||Lucifer Sam
|Take Up Thy Stethoscope And Walk||Matilda Mother
|Matilda Mother||Pow R. Toc H.
|The Scarecrow||Take Up Thy Stethoscope And Walk|
|The Gnome||Interstellar Overdrive
|Interstellar Overdrive||Chapter 24|
Note also that the double-album A Nice Pair is almost, but not quite, 'Piper.' The version of 'Astronomy Domine' that appeared on the original US Capitol pressings of ANP is not the original studio version, but was instead the live version that appears on Ummagumma. Other than that, it is identical to the original UK 'Piper.'
