[indianapolis]

In the above BBC special shown on Boxing Day, does anyone know the name of the poem which Roberta, the sister of one of the dead girls, read during her funeral?

Mary Lambs "What is Love?"

Love is the passion which endureth,
Which neither time nor absence cureth
Which nought of earthly change can sever
Love is the light which shines for ever.

What cold and selfish breasts deem madness
Lives in its depths of joy and sadness:
In hearts, on lips, of flame it burneth;
One is its world-to one it turneth.

Its chain of gold-what hand can break it?
Its deathless hold-what force can shake it?
Mere passion aught of earth may sever,
But souls that love-love on for ever.
