"Baba Yetu" is a song by composer Christopher Tin. It was composed in 2005 when video game designer Soren Johnson, his former roommate at Stanford, asked Tin to compose the theme song for Civilization IV and was sung by Ron Ragin and the Stanford Talisman. For its re-release in Tin's debut album Calling All Dawns, it was sung by Ron Ragin and the Soweto Gospel Choir. [Wikipedia]
