Spooky - G-BSSC is a PA28 I've been known to fly on occasion, though not for a few months now (so I can plead innocence for this one). It is (or at least was, last time I looked) used by a club/school at Norwich, so it could well have been a student you were listening to.
But why is it you get two similar callsigns just when you could do without the complication? First time I ever came across it was ... on my PPL final skills test, with all the other pressures that involved! Thankfully the examiner let me off the first couple of offences of "G-NO blah blah" as I remembered to spout it in full after a while.
