STONY BROOK - A group of young singers from Stony Brook is warming its voices up for a very special event: it is traveling to Washington this weekend to perform at President Barack Obama's inauguration celebration. 

The Stony Brook School Chamber Singers has been rehearsing a South African song called Bonse Aba for the occasion. The 16-member group will play traditional South African instruments during its performance.

The group is scheduled to sing at around 3:30 p.m. on Saturday. They will be among students from 40 other schools across the country who are performing in the inaugural ceremonies.

President Obama will be officially sworn into his second term on Jan. 21, which is Martin Luther King Day, but the inaugural festivities are being spread out over four days.
