Where is Bongo-Bongo land?

The President of Gabon from 1967 to 1973 was Albert-Bernard Bongo.  On his conversion to Islam he changed his name to Omar Bongo, and remained president for another 30 years. He was succeeded by El Hadj Omar Bongo.

There were two acting presidents in 2009, Didjob Divungi Di Ndinge and Rose Francine Rogombé. Didjob did the job for 5 weeks and Rose blossomed for the next five months before the current president, Ali Bongo Ondimba, took office.

On that basis Bongo-Bongo land is Gabon..
