Going onto the main topic for the article....one of the songs that was included in the intense medley was The Peanuts'（ザ・ピーナッツ）"Jounetsu no Hana" (Passion Flower). If the melody does sound familiar, it is based on Beethoven's "Fur Elise". I mentioned some years back in the blog for "Kiss wa Me ni Shite"（キッスは目にして）, which was another kayo take on Ludwig's masterpiece, that I had remembered hearing this old song on audiotape by either The Peanuts or Candies. As it turned out, it was "Jounetsu no Hana".
Now, The Peanuts' song, released in 1959, wasn't a direct adaptation from the legendary composer but was probably adapted from Fraternity Brothers' "Passion Flower" and its cover by Italian singer Caterina Valente in the late 1950s. For the Japanese version, Takashi Otowa and Tetsu Mizushima（音羽たかし・水島哲）wrote the lyrics for The Peanuts. However, the melody for all three acts mentioned here kept its Latin edge.
The Peanuts once again released "Jounetsu no Hana" almost a decade later in 1967. This version had different lyrics and an arrangement that was very Burt Bacharach perhaps with even a bit of Herb Alpert thrown in for good swinging measure.
"Jounetsu no Hana" would make for a good comparison with the later 50s rock n' roll "Kiss wa Me ni Shite". Anyways, I can't really say whether Beethoven rolled over in his grave with either version.
