On YouTube I found a film clip containing this remarkable song, "Porque te vas" by somebody called "Jeanette." After a bunch of poking around, I that Jeanette Dimech was sort of a one-hit-wonder from the 1960s and this song was her claim to fame. The film clip is a scene from Carlos Saura's 1976 film Cria Cuervos (Raise Crows, a Cannes Film Festival winner) where Jeanette's "Porque Te Vas" plays. "Porque Te Vas" has been covered many times without the lo-fi charm of the original. Below is a Japanese anime mashup of the original song recorded in 1974. The anime below is called Midori ho Hibi, which a pun on the Japanese "Golden week" holiday happening now in Japan (Read full details here). Enjoy the iPod ready MP3 (5MB) of the original recording of 1974 song although with the hamster noises of the 1976 film.
