Caller Dies On Live Radio Phone-In Show Officials: Heart Attack Likely Responsible (KUTV) A caller to a British radio phone-in show died while on air, the program's host said Friday as he described his shock. The regular caller, known only as “Terry,” had telephoned in to a late-night debate yesterday on Liverpool's Magic FM 1548 station in northwest England when the line suddenly went silent. Disc jockey Pete Price was so worried that he abandoned his show and sped to the man's house – but it was too late.
