name='batman']Many years ago, I think in the mid-late 70s, I remember watching a late night ghost story on TV. It featured a team of psychic investgators in a house where the ghost of (I think) an old pirate/reprobate was doing the haunting. The story focused on the team setting up there equipment with odd things happening from time to time. Finally, the old boy put in an (invisible) appearance and trashed the equipment and (I think) frightened the investigators either to death or out of their minds. I am fairly sure it was on the BBC. For some reason I think Nigel Davenport was in it but I cannot find anything resembling it on his IMDB page. I used to think it was 'The Stone Tape' so I bought that and, although 'The Stone Tape' is excellent, was disappointed to find that it wasn't theone I remember. Does anyone else remember this and can put me out of my misery?
