*young girl pops head over parrapit*I have to say your amazement amuses me.
I'm 21, & I leart long way 2 Tipperary & pack up your troubles, at first school, I was in class 2 at the time, & still of the age when words would instantly be remembered with out effort. I've therefore had them within easy recall ever since. the same goes for 'run rabit' which i must of learn't at an even younger age from my parents.
& sport & bawdy folk songs have always gone hand in hand, Just think of rugby club songs! though my upper schools CCF was as bad! [CCF = Combined Cadet Force. i.e. teenage boys & girls playing @ soldiers]
