Michel Sardou speaks to Augustin Trapenard in a two-hour documentary on France 3. Since 1965, Michel Sardou has sung a lot and talked some more.

“Sardou. Self-portrait” is a delicate and perilous exercise: the singer speaks, but does not confide; tells by twisting (sometimes) the facts; repeat by changing version. This March 29, Sardou will give his last concert in Brest, in the south of France.
