"Lettre à France" is a single by French singer Michel Polnareff that was released in 1977. The artist had been living in California since 1973, in part due to financial problems. The song, whose title means "Letter to France" in English, is about living in exile, and is a love song to his home country.
The single sold 476 000 copies, allowing Polnareff to return to France to partially resolve his tax problems.
