THanks Swannie, Ian and Rys. YOur comments have cheered me up no end (I'm temporarily sidelined from most activities with a painful sciatic nerve triggered by a dodgy L5-S1 - now there's a code number that even Mac may not know, but he probably does!)
BUt this new mix would never have seen the light of day without the attentive, constructive and clear guidance of the forum, so thanks to all.
