He participated in magie but sang completely differently than the voice we are used to
his part on the song magie is "mvula mi o ga makalekela....." and there is his song shambuyi which was completely sung by koffi 
 if i remember well,sam did not make it to the team who was to usa so his song was done by koffi same for modogo( koffi only went with babia suzuki and willy bula) but luckily for modogo his song was already recorded  in kin

Sam did three albums with Babia : Magie,V12 and Droit De Veto and i agree with abarambwa their chorus (Magie-V12 era) was the best Koffi ever had. Too bad that in 97 he choose only 4 of them (Ultimatum-Loi era).

Sam did only sung in Droit de Veto with Babia and also in the unreleased version of Ultimatum recorded in Kenya, which was mysteriously lost.

He also sing with Babia in Magie (He noticed it later in this interview) and V12 he did his first QLI song "Shambouyi" in Magie and he have 3 or 4 vocals in this album. I didn't know they recorded Ultimatum in Kenya first I was surprised when I heard that because I thought Koffi picked only 4 singers for this album and left Babia,Eric and Willy Bula in Kinshasa.

was the song Dessin Anime recorded in the Magie-era ? or was it from the Kenya recording ?

Babia Ndonga Chokoro is another of the many unsung heroes of QL. Loved his voice to death. That melodious voice u only get from the likes of Babia, Eric Tutsi, Chai and Adjani. So sad none of them seem to end well . Could their be something like the 'curse of the voice'?

I heard it was recorded for V12 but Koffi deleted it because Scola Miel left QLI.

That's so true!  Erick Tutsi was another one Koffi also messed about, he returned to Quartier Latin was made to mingle with the small boys Koffi was calling 'Les Mineurs' as an ordinary singer so didn't last long and he was out again,no clue where he is now.
