In 1985 and 1986, Gall worked with Berger, Richard Berry, Daniel Balavoine and for the benefit of Action Écoles, an organisation of schoolboy volunteers which collects essential food products in France for African countries where famine and drought prevail. On 14 January 1986, during a trip to Africa, Balavoine tragically perished in a helicopter crash. In 1987, the song "Évidemment", written by Berger and sung by Gall, was a moving homage to their lost friend. The song appeared on the album "Babacar".
