From the recording Treat You Right (feat Sir Louie, David Marcus, Paul Lukeman, Equanim)
Sounds like Marvin Gaye, Kenny G, Drake and K-OS made a track together.
Equanim heard a loop David Marcus made and was inspired, asked to work with it. Added production, keys, and a verse. Sir Louie did ad-libs and recorded a hook. Paul Lukeman of Luvboat went off on saxophone.
