01 - Love is the seventh wave - Japan sample issue in purple sleeve - ALAM-121 For this single, like all the other Japanese "sample copies" ,there were very few copies pressed. The cover has the same picture as all the other releases, but the main difference is that instead of being a colour picture, it is purple and white. In fact, the whole insert is purple and white. Also the back of the insert is completely different. The track listing is surprising too, with the "New Mix" version on the A side, and the "Album version" on the other. It should be pointed out that "Love is the seventh wave" was not released in Japan as commercial 7" single, but was however released as a commercial 12" single. Back to 10 rarest 7" list.
