Several country superstars have "come together" for a new performance video which aims to raise funds and increase awareness for St. Jude Children's Research Hospital. Big & Rich, Keith Urban, Darius Rucker, Lady Antebellum and Randy Owen join more than 30 other celebrities singing "Hey St. Jude," a special version of the Beatles classic, "Hey Jude," released in conjunction with National Childhood Cancer Awareness month.

The video, which includes several St. Jude patients, as well as doctors, nurses and other medical personnel, also features Jennifer Aniston, Ellen DeGeneres, Dr. Oz, Jimmy Kimmel, Jordin Sparks, Betty White, Michael Jordan, Robin Williams and many more.

The clip honors 50 years of St. Jude's efforts in researching and treating childhood cancer and other diseases. It's a cause John Rich is proud to stand behind.

"St. Jude Children's Research Hospital holds a very special place in my heart," the singer explains. "I don't know how you could spend your time any better on this earth than to support something like St. Jude. It's truly God's work."

Earlier this year, John hosted a star-studded benefit which included Darius, Kellie Pickler and Jeff Foxworthy. In 2011, he raised more than $1 million for St. Jude by winning the 11th season of "Celebrity Apprentice."
