Sour note for man with golden voice

A feel-good story about a homeless man with a radio-voice from heaven has been soured by a war of words between two American broadcast networks.

Ted Williams, a former DJ who had fallen on hard times, was a roadside beggar until a video of his singing went viral, bringing him more job offers and interview requests than there are stations on the dial.

Now CBS is accusing NBC of blocking a meeting it had set up with his mother, Julia, whom he had not seen for 10 years. NBC claims its rival has sabotaged its own plans for a joint interview.
