I'm trying to recollect pretty old composition, from the end of 80s - beginning of 90s.
I've already check almost all "best of ..s " compilations on youtube - no luck, probably it was not very popular.
Here is what i remember: not sure, but think there is no lyric, may be some scat, melody
starting steady, guitar and piano, than rhythm going faster and faster, guitar start sounds more like "flamenco" style, at background you may hear woman's shouts. (So yes, overall composition's rhythm imitating coitus, but nothing like "erotic music") At the end melody is slow again. One more detail - in the middle of composition you may hear loud and quite realistic finger whistle, when i heard it first time i (and most of my friends who later listened it) was sure it's really somebody call us from the street..
This is all i remember.
