'No More Chemo' song celebrates 3-year-old's big victory

A 3-year-old girl battling acute leukemia is back home in Tennessee after a very special send-off from the hospital.

Doctors and nurses at St. Jude's Children's Research Hospital in Memphis were captured in cellphone video singing a song they call "No More Chemo" to little Hadley Gray.

After six months and four rounds of chemotherapy, Hadley was finally given the all-clear to go back home.

Little Hadley is now cancer free.
