While Robin Gibb remains in a coma in a London hospital, his family is singing and playing music to him in hopes of reviving the legendary artist.

In an interview with Ireland?s The Impartial Reporter, Dwina Gibb, wife of the 62-year-old Bee Gee, said?three of Robin's children ?- Robin-John, Spencer and Melissa -? have been playing music to "try and bring him back to us."

She also told the newspaper, "His brother Barry, his wife Linda and son Stephen came over from America. Barry was singing to him. Thousands of people are saying prayers every day."

The singer has been battling colon and liver cancer for the past two years, and fell into a coma in April after contracting pneumonia.

Robin and Dwina have been married for 28 years and share one child, Robin-John. Gibb's older two children are from his first marriage, and he also has a young?daughter, Snow,?with his former housekeeper.

Dwina Gibb, a former druid priestess,?has discussed the couple's unconventional open marriage publicly.

Robin Gibb once told radio host Howard Stern, "My wife is a lesbian and I love it."

But Gibb later gave interviews saying their life had calmed down. "We actually have a very conservative relationship -- more so than the average couple," Gibb told the Daily Mail in 2010.?"We don't drink or smoke. We're not partying all the time."

"Their love for one another is very tight," David N. Meyer, who is writing an unauthorized biography on the Bee Gees, told ABCNews.com.
