Song was also part of the Cameroon squad for the 2008 Africa Cup of Nations. After a 4–2 loss to Egypt in the Group C opening match, the veteran defender led his team to wins against Zambia (5–1) and Sudan (3–0). In the first game against "The Pharaohs", Song's nephew Alex made his international debut for Cameroon, joining Rigobert on the pitch at half-time. The captain then carried the "Indomitable Lions" to the knockout stage, in which they defeated Tunisia (2–3) and Ghana (0–1) before losing the final to Egypt 1–0. The only goal, made by Mohamed Aboutrika, came after a mistake by Song, who covered his face with his shirt during the opponent's celebration.
