 A sci-fi folk rock song, similar in style and genre to David Bowie's "Space Oddity." This was Smile's only release at the time, but because Mercury Records failed to give it any promotion, it had no chart success. That lead to Tim Staffell leaving the band, Freddie Mercury joining and the formation of Queen.

Originally a 1984 song, Smile recorded their version for the "Earth" single. This version is pretty close to the 1984 demo versions, but is a much cleaner recording.

The Smile version here is not too different from the later Queen versions, though instead of piano, it features acoustic guitar in the quiet sections. The song was pretty complete by the time Queen recorded it. The later Amigo version, however, is vastly different.

Brian and Tim share the lead vocal on this track, which would later be recorded by Queen during the sessions for their first album. It's a mellow blues number.
