Both songs were never part of an official release, but appeared on a demo acetate which was used as the source for bootleggers several times. It later appeared on a CD accompanying an Italian book about Syd Barrett called "Fish Out Of Water" in outstanding quality; this CD is now the most common source for bootlegs of the song. During the same session two other songs were recorded, titled Double O Bo and Butterfly, which until now have never seen the light of day.
