I have managed an amount of reading since your replies yesterday and it has been facinating seeing the botanical connections to songs and their 'hidden' meanings. It is almost like Heraldry using symbols but we use words as symbolic instead of painted objects.

I will always have a fondness for the song itself but now it will never be the same and could mean something different each time it is sung. Such a pity we cannot speak to the person who wrote. They still speak to us :-)

Best wishes
