Timmy Mallot of all people just posted this on soundcloud - a 2 hour set from Terry Hall, last heard in 1985.
Stop what you are doing, it's worth it.
Terry Hall Easter special Piccadilly Radio, Manchester TX: 8th April 1985 21:00-23:00
I asked 25 year old Terry Hall if he'd like to have a go at presenting his own show. There were just the two of us in studio 2 at Piccadilly Radio with a pile of records and a delightful shy and slightly nervous Terry. I played the records in real time, and encouraged him to tell his story and he gets more confident as the show progresses. Enjoy the revelation of his inspirations and a personal insight into the processes of his recording. There are some joyous surprises coming up The tape has been in the loft since 1985.
