Name that tune

At breakfast with some of the folks from Kenya and DRC the second morning, our conversation about politics was interrupted when the guitarists from the evening before walked by the dining room and talk turned to music and singing. Most of the conversation was in Swahili, so I asked for some clarification.
“Congolese sing very well. Perhaps he will sing for you if you ask,” a Kenyan says of our DRC colleague. And then looks at me.
“I am a terrible singer. I can’t sing to save my life,” I say. [ those of you who know me know who dreadfully true that is]
And at that point we return to our conversation about a man who used to be a minister in the government.
“Why is he no longer minister?” I ask.
“Well, when you are minister, you must know how to sing. To sing the tune of the government,” one of my companions says.
And then another adds, “Like you, he could not sing to save his life.”
