When I Was Young Mother Nature Was Also Cross

When I was young Today I still remember all of it The same as when I was a kid Don't remember this virus though Just measles, coughs and some serious colds Along with chicken pox and whooping cough Had them all as well me But i had no BCG... to save me from the TB Thankfully one I have not yet needed. I do though think we can find a way To wave this virus on it's way As I am old and you are young So the fight has just begun You need to work out what it was That made mother nature cross Best DAMOx
