If you buy these tracks from Skam's MP3 download store, "Aquarius" has a running time of 6:10, and "Chinook" is 7:25. What's on the MP3s are the same versions as what's on the original 7" single. Presumably, the MP3s were made from the master tapes, so their track times are probably more accurate than what's listed here at discogs. (I guess the timings listed here were estimated from playback on a turntable that was running slightly fast.)

Aquarius is based on the first minute or so of Aquarius from the Hair original soundtrack (not the Original Broadway Cast recording though which is nothing like it) to the point of being a blatant steal! But at the same time the sheer subtlety of the re-editing makes this a hugely original work in the way it transforms the original completely out of context and genre.
