listen at the beginning of the long version of the generique, roga says " macconnerie'"(masonry) then "equerre" i dont know the adapted workd in english for that particular context (but in a normal context its set squarre) which from what i saw in a documentary about african presidents and freemasons is one of their symbols
then dedicates a guy as a "master mason"
roga is extremely close to president sassou family who are in it so maybe they introduced him
