Serge Gainsbourg's "Aux armes et caetera" album was very late 1970s. His reggae version of "La Marseillaise" infuriated conservative France when it came out in 1979. I thought it was great to hear Bob Marley's own back-up singers, the i-Threes, sing "aux armes, et caetera". ;-) Rita Marley, Judy Mowatt and Marcia Grifith. all also had their own solo carreers.
