"Rock n' Roll Widow" was on my compilation CD of her BEST songs (as it probably has been on any of her BEST discs), and unlike those two other Uzaki-and-Aki productions, there was much more of a feeling of fun and abandon despite the "widow" part of the title. Perhaps the widow was dancing on top of her hubby's grave but that is about as dark as I will get in my speculation. In any case, the song was Yamaguchi's 30th single released in May 1980 (I realize that she was not far from retirement, but it's hard to imagine her as anyone other than that representative 70s songstress), and on hearing the song, it seems like her two collaborators just told her to go nuts. And she truly thrust in the growls and the yells. I'm sure her fans launched their eyebrows when they first heard the song. My favourite part of the song is when she belts out the "Kakko, kakko, kakko..." with the harmony gradually phasing in.
Then I saw her performance of the song on shows such as "Yoru no Hit Studio"（夜のヒットスタジオ）. She sported that big hair, the face paint and the fashion, and put on some rather interesting dance moves such as a furyo stance at the very beginning. In the J-Wiki article for "Rock n' Roll Widow", the writer also mentioned about her sashaying up and down her guitarist's back during the instrumental. For a lady who I usually imagined as being pretty static in her performances, Momoe-chan just went Disco Queen...or Rock Queen, perhaps. In a way, it was like watching Olivia Newton-John's Sandy character undergoing that transformation at the end of "Grease" from Sandra Dee to leather-wearing she-devil.
