Here in the UK the BBC ran a series of programmes entitled "My familt at war" it featured celebrities whose relatives had fought for the allies in WW1, it was a moving series, with many a celeb reduced to tears when they discovered the personal story of their ancestors, often stories that had gone unspoken due to the horendous nature of the conflict.

The last episode feature Rolf, his father was born in Wales, but had emigrated to Australia whilst in his early teens, at the outbreak of WW1 he returned to Britain as part of the Australian army, his younger brother had also signed up, but it was discovered that he was underage, and had to stay in Wales whilst his older brother (Rolf's dad) went to war, eventually the 2 where re-united in the trenches at Somme, they where in different regiments bought both where wounded in the same battle.
Unlike the song "2 little boys" that had a happy ending, Rolf's father never saw his brother again, he died at the end of the war.

This discovery lead Rolf to re-record the song, and he stated quite movingly that it now had a bigger deeper meaning for him.
