Tom Joyner performs during the Mandela Day: A 46664 Celebration Concert at Radio City Music Hall on July 18, 2009 in New York City.
Joyner said: "We didn't make it to Haiti, but we're on the air."
The Haitian capital city's airport, damaged in Tuesday's quake, is congested with relief flights and air traffic has been limited.
American Airlines, the main carrier to Haiti, suspended commercial flights Wednesday and instead has been transporting relief supplies.
