Original mono issue. The mono mixes of the songs were done at a different time and are different than the stereo mixes. This mono release was simultaneous with the release of the stereo version.
Tower Records altered the songs on the album from the original British release to include their single See Emily Play, and dropped the songs 'Astronomy Domine', 'Flaming' and 'Bike' from the record. Also, names of the songs 'Pow R. Toc H.', and 'Take Up Thy Stethoscope and Walk' are misspelled.
