I have never, ever heard anything like it, and I worked in radio for a long time. He sounded like he was in tremendous pain. He also went to the bathroom while his partner and a called (a woman who had survived a suicide attempt) talked - his partner prayed very urgently for him.
When he came back, he said he had taken the rope from around his neck, and actually banged it against the mike several times.
He may be an engineer or producer, someone with access to the studio and knowledge of operating the board, phone lines, and who kept a reasonably well-spoken monologue going. I’ve heard other people who were very drunk and morose talk, and they just sounded drunk and morose. He had a lot on his mind, and I think felt absolutely cornered spiritually.
And yes, there were lots of word-bombs.
I continue to pray for him.
