Hi Prof, yes, I had several extra chairs and all sorts of other stuff too. I have got FJ's umbrella and his chair, I was sure I put your chair in BG's boot too, but I don't have it though so don't know where it's gone mate. Sorry.
Was this a green chair, or alternatively a stripey one?
Two such chairs were near me when I left, assumed to be the property of Keith, the Phantom Camaro driver, but this assumption was 3rd hand, so they might not have been.
