Sarah Mentioned "(Pack Up Your Troubles in Your Old Kit Bag and) Smile, Smile, Smile!" & "It's a Long, Long Way to Tipperary".I discovered courtesy of our children's primary school concert that these two songs counterpoint each other perfectly.
The audience was divided into 2, one for each song, with pack up your Troubles starting on the word "Long" in Its a long way to Tipperary.
It was hilarious trying to stick to the song you were allocated, while listening to the other. Try it!
