Wha-Ha-Ha released two amazing albums in the early eighties as well as an EP. Their material was also released in Europe on Recommended Records as a compilation. It's a weird combination of jazz, Rock In Opposition, Japanese melodies, pop songs, unexpected transitions and synthesizer sounds. They remind me a lot of Japanese RIO band After Dinner, also due to the female vocals. I recommend you to check out all the other Wha-Ha-Ha material.
The first song on this single was reissued as a bonus track on a CD in 2003, but the second song hasn't been re-released as far I know. Both of the songs do not appear on the albums.
