George Henry Powell (27 April 1880 – 3 December 1951) was a British songwriter who, under the pseudonym George Asaf, wrote the lyrics of the marching song Pack Up Your Troubles in Your Old Kit Bag.
While you've a lucifer to light your fag, Smile, boys, that's the style. What's the use of worrying? It never was worth while, so Pack up your troubles in your old kit-bag, And smile, smile, smile.
