When it comes to the vocal group Circus（サーカス）, I will always remember the quartet for "Mr. Summertime", the cover of the 1972 Michel Fugain song "Une Belle Histoire".
Well, I found out that their 3rd single following "Mr. Summertime", "Ai de Koroshitai" (Kill With Love), was another Michel Fugain cover, this time of "Chante la vie chante" from 1976, I believe. Released in July 1978, just a few months following "Mr. Summertime", "Ai de Koroshitai" has got a bit more of the Latin spice infused in there, trying to get folks onto the disco floor.
I will be honest...I'm not sure whether Circus' choreography during their onstage performances would have gotten viewers off their duffs here. Well, the song is still pleasant as an exotic kayo and perhaps even as a City Pop tune.
"Ai de Koroshitai" didn't rank as highly as "Mr. Summertime" but it still placed in at a respectable No. 28 on Oricon. Pierre Delanoe and Fugain were responsible for the creation of the original song but it was Rei Nakanishi（なかにし礼）who came up with the Japanese lyrics. The song was also a part of Circus' 1st album, "Circus 1"（サーカス1）, also from July 1978.
This is the original "Chante la vie chante" by Fugain. It's a bit more laid-back.
