Robin Gibb of the Bee Gees has regained consciousness, and is communicating with family members at the hospital. Over a week ago, he contracted pneumonia, and went into a coma.

He's still in bad shape, but his doctors released a statement saying they're "confounded" by his, quote, "indomitable fighting spirit and remarkable physical endurance."

Three days before, they told his family it wasn't looking good and that it was, quote, "very likely that Robin would succumb to what seemed to be insurmountable obstacles to any form of meaningful recovery."

But miraculously, he woke up and it may have happened thanks to his older brother Barry Gibb's voice.

Robin's wife says "Barry was singing to him" while he was in the coma and they've been playing his favorite music to "try to bring him back."

There's no word what songs those were.

Robin has had a ton of health issues over the past year. He's had intestinal problems and was diagnosed with colon cancer, which has spread to his liver. He's also had liver failure, causing brain swelling.
