As I mentioned in the article for songstress Anri's（杏里）"Wedding Shower", I got her 1996 album, "Angel Whisper" based on her contribution to the Atlanta Olympic Games, "Ano Natsu ni Modoritai"（あの夏に戻りたい）. The fun "Wedding Shower" was also included on that 18th album of hers, and another track was the intriguing "Antonio's Song".
I had never heard of the original by Michael Franks...and for that matter, I had never heard of jazz singer Michael Franks, which goes to show how educational my voyage into Japanese popular music has been. It's even pointed me back to old American pop tunes from the 70s. In "Angel Whisper", Anri performs a duet with Franks that has hints of the original, and it has that quiet bossa nova sound that I have come to enjoy. Considering the relaxing pace of the song, I gather that Anri had to slow her delivery a fair bit.
Gradually, I was able to obtain a copy of the original through an AOR compilation album, and I actually like it better than the duet version between Franks and Anri. It's got more of that bossa nova and the sophistication that had me thinking clinking wine glasses and fancy dress ballroom. "Antonio's Song" was a track on Franks' 3rd studio album, "Sleeping Gypsy" from 1977. There is some mystery in the melody and also some mystery in the title and lyrics. I'm not 100% positive about who Antonio is...perhaps it might be one of Franks' heroes, Antônio Carlos Jobim, one of the pioneers of bossa nova back in the 1960s.
