Self-explanatory to Britishers in the 1990's, this
description of unruly hair
will puzzle the rest of us, so:
1. Terry Waite
served as the Anglican
Church's international diplomacy negotiator. In 1987, he was himself taken hostage in Lebanon and held mostly in solitary confinement until his release in 1991. He's a well-known public speaker now.
2. "Allotment" in Britain
is an urban rented garden patch.
Hence, Terry Waite
's allotment would
be untended and weed-choked.
I haven't determined if Waite
actually was an allotment holder
at the time of his confinement.
