So I was listening to A La Queue Leu Leu, really taking the songs in. As I got to Calmement, I was less than a minute in when I realised something. This was the only other song on the album, apart from Ligne 11, without any musical backings from Al Nzimbi or Philippe Guez. Instead, you have Papy Kakol and Thierry Synthe playing throughout the entire song rather than just the sebene. Even the intro was different; it just cut to the chase instead of starting with any keyboards.
I'm saying this because having familiarised myself with Al and Philippe's arrangement styles, I could tell who played on which song in which period. Furthermore, they also played keyboard on top of live drums on albums from that period and earlier (Al arranged Kibuisa Mpimpa but Djudjuchet played on the rumba parts; Philippe played keyboards on Solola Bien with Djudjuchet being the drummer and Maika Munan arranging the songs), but I didn't hear any of their usual sounds on Calmement. This was an all-Maison Mere song, right down to the Zenith intro. For all I know, this was probably the first song recorded for the album.
