Luke Bryan, Randy Owen, Clare Bowen and Chip Esten took the stage of the Grand Ole Opry this week for St. Jude Country Cares for Kids Concert.
The show raised money for St. Jude Children's Hospital in Memphis, which treats kids with childhood cancer. St. Jude uses the most cutting edge technology and doesn't charge a cent, taking the financial burden off of families.
Luke says he can't imagine what parents of sick kids have to deal with.
"You tuck them in at night. You say your prayers they go through this life safe and unscathed. And you certainly pray that you never have to deal with what the parents of the children of St. Jude have to deal with."
It costs about $2.4 million a day to run the hospital.
Clare Bowen was diagnosed with end-stage cancer when she was four. Doctors gave her two weeks to live. Danny Thomas founded the hospital in 1962. St. Jude is named after Danny's patron saint, but it is not a Catholic hospital.
