PHILADELPHIA - CBS Corp. fired a radio host and a radio station's program director over a racist song that was performed on the air in March.

The song played on WYSP-FM during host Kidd Chris' morning show was "highly offensive and completely inappropriate for broadcast on our airwaves," CBS Radio spokeswoman Karen Mateo said in a statement Friday. "When senior management of the station learned that it had been played, they took immediate steps to prevent it from ever appearing on the station again."

The Philadelphia Daily News reported on its Web site Friday that it had obtained a transcription of the song's lyrics, which derided blacks and included numerous racial slurs.
