After all that effort from various posters to point me/us in the right direction I'm afraid to say that the hoped for outing didn't materialise. We have been suffering from a dreaded lurgie which has left us both wishing that we didn't have to eat anything at all. No ones fault, just one of those things. Fruit we think.
Many thanks to all who posted:As usual, instructive,full of wit(WIT) and repartee.
