My favourite version by Gracie Fields sung live to the troops!

Wish me luck as you wave me goodbye
Cheerio, here I go, on my way
Wish me luck as you wave me goodbye
Not a tear, but a cheer, make it gay
Give me a smile I can keep all the while
In my heart while I’m away
Till we meet once again, you and I
Wish me luck as you wave me goodbye
Wish me luck as you wave me goodbye
Cheerio, here I go on my way
Wish me luck as you wave me goodbye
Not a tear, but a cheer, make it gay
Give me a smile I can keep all the while
In my heart while I’m away
Till we meet once again, you and I
Wish me luck as you wave me goodbye…
Wish me luck as you wave me goodbye
Cheerio, here I go, on my way
Wish me luck as you wave me goodbye
Not a tear, but a cheer, make it gay
Give me a smile I can keep all the while
In my heart while I’m away
Till we meet once again, you and I
Wish me luck as you wave me goodbye
Wish me luck as you wave me goodbye
Cheerio, here I go, on my way
Wish me luck as you wave me goodbye
Not a tear, but a cheer, make it gay
Give me a smile I can keep all the while
In my heart while I’m away
Till we meet once again you and I
Wish me luck as you wave me goodbye…
Goodbye everybody, I’ll do my best for ye
