Billy Murray's original release was titled "When We Were Two Little Boys", but most every subsequent recording has just been titled "Two Little Boys".
Lyrics start out - Two little boys had two little toys Each had a wooden horse Gaily they played each summer's day Warriors both of course One little chap then had a mishap Broke off his horse's head Wept for his toy then cried with joy As his young playmate said Did you think I would leave you crying When there's room on my horse for two Climb up here Jack and don't be crying I can go just as fast with two When we grow up we'll both be soldiers And our horses will not be toys And I wonder if we'll remember When we were two little boys
