I did this one because my brother was practicing it a week or so before. Its an excerpt from a HUGE poem, but my teacher was cool with it. It has a good rhythm too it so its not bad to remember.
Its entitled "Ballad of Reading Gaol" by Oscar Wilde.
These were the lines I used:
The man in red who reads the Law
Gave him three weeks of life,
Three little weeks in which to heal
His soul of his soul's strife,
And cleanse from every blot of blood
The hand that held the knife.
And with tears of blood he cleansed the hand,
The hand that held the steel:
For only blood can wipe out blood,
And only tears can heal:
And the crimson stain that was of Cain
Became Christ's snow-white seal.
