I thought that may be a song and in my search for an artist I found this information on
www.truthorfiction.com:
"The Truth:
According to the American Cancer Society, the email is a hoax. The girl in the story is never identified, the American Cancer Society has not made any such commitment, there is no way for forwarded emails to be accounted for even if someone wanted to make a donation for each one, and the professor named at Yeshiva University, Dr. Dennis Shields, says he never had anything to do with any such story. If you dial his number, you get a recording saying the story is not true. There are several versions of this email making the rounds of the Net. Some simply say this is a poem written by a dying girl. Others say the little girl gave it to a medical student. Others say the poem is being circulated by a doctor."
