This song was composed in honour of Alhaji Bamba Bodian or Ledjè, a wealthy merchant of the XIX century, king of Sumakunda (Gambia) who was also a generous patron (“djatigui”) to the griots of Gambia. Many Gambians consider him the forerunner of the modern state of Gambia.
“Bamba” was a nickname which he was honoured because, as the legend tells, he used to feed crocodiles (“bambo”) by the Gambia River.
Some korafolálu recorded this song, but the one whose name is attached to the song is definitely Lalo Keba Drame who recorded a brilliant version in 1967. Another virtuoso korafolá gave a classic version, Alhaj Bai Konte, imitated by many korafolálu but never equaled.
You can check for modern versions by Ba Cissoko or Dawda Jobarteh.
