South Africans may have been largely left out of the main celebration for Nelson Mandela's 90th birthday when London hosted a concert in his honor last month. But that hasn't stopped individual artists from paying tribute to the global icon on his big day.

Poseletso Sejosingoe, a theater performer in London's West End and runner-up in South Africa's 2005 Idols contest, has recorded "Madiba Nine-0," the closest thing the country has to an unofficial anthem for the first democratic President of South Africa.

The song has yet to be released but has found its way onto adult contemporary radio countrywide in the days leading up to July 18 and will feature on Poseleto's debut album which is due for release in October through Cape Town Sound.

The Cape-based label is run by Patric Van Blerk, a veteran of the South African music industry who also co-wrote the ballad with songwriting and business partner, Natasha Simonne.

Other artists who have issued tribute songs include controversial "People's Poet" Mzwakhe Mbuli. His upcoming album -- which will be issued in the next month by EMI South Africa imprint CCP Record Company -- includes the track "Madiba (Long Walk To Freedom)" in reference to the struggle hero's autobiography.

In spite of all the fuss, Mandela is spending his birthday in his childhood village in the Eastern Cape with his family.
