Keith Urban and fellow Australian Olivia Newton-John's duet, 'Sunburned Country,' will be among the collaborations on the CD, 'Olivia Newton-John & Friends: A Celebration in Song,' being released in the U.S. on September 3. Urban and Newton-John wrote the song together. It was originally featured on an album released only in Australia in 2002.

A breast cancer survivor, Newton-John, who turns 60 in September, established the Olivia Newton-John Cancer and Wellness Centre in Melbourne, Australia, "a comprehensive center for the treatment, care and research of all types of cancer to help heal the whole person: body, mind and spirit." Royalties from the duets project will benefit the organization.

In addition to her duet with Keith Urban, the album features the 'Grease' star's collaborations with Barry Gibb, Richard Marx, Cliff Richard and a number of other Australian artists.

Interestingly, although they both call Australia home, neither Olivia Newton-John nor Keith Urban were born there. He was born in New Zealand, and she was born in England.
