He was talking about Brian Keenan - that's how he himself was taken hostage, negotiating for the release of John McCarthy, Brian Keenan and I think 4 other hostages.....
Apparently after 2 years in solitary confinement, they were going to release him, took him to a proper house (as opposed to a tiled cell) and guarded him there for a week ready to release him at a time and place to be decided, at the end of that week the Iran Contra situation kicked off, changed their minds about the release and they took him back to his cell and kept him there another 3 years because they thought he was involved with arms dealing - can you imagine being so close to freedom to find yourself back in your cell alone for another 3 years!!!
