Cant help with Joanne Whalley but a few years back on a BA Flight from Glasgow to Heathrow I did sit next to joanna lumley who had the window seat, mid flight the Flight Crew were dishing out Tea, Coffee and Scones with mini Jars of Strawberry Jam and Cottage Cream, She refused Hers, in fact her exact words were "Oh No!", with that I said to the Stewardess "I'll have Hers", and proceeded to tuck in, I can remember it now, all I got from her was a dirty look from the corner of my eye as I was stuffing into the Jam and Cream, nothing was said but at point as I was looking out of the window, she did say "Youve Got Cream on your nose" and then proceeded to look the other way to look at the window.
Well it did involve a Joanne and Cream but thats as far as it went Ron,
get well soon.
