"PRIMETIME LIVE" EXPLORES STORIES OF "THE UNEXPLAINABLE," INCLUDING A MAN WHO MYSTERIOUSLY DEVELOPS A REMARKABLE MUSICAL GIFT AFTER BEING AFFLICTED WITH PARKINSON'S DISEASE, THURSDAY, JUNE 30 ON ABC

"Primetime Live" co-anchor Chris Cuomo reports on three remarkable stories that seem to defy reason, including that of Greg Rice, who almost lost everything to a crippling disease but also gained something he never could have imagined. Rice, of Dover, MA, saw his world turn upside down when he was diagnosed with Parkinson's Disease. A man who worked hard and played harder suddenly found it difficult to perform even the most basic tasks. But the disease also seemed to open an unexpected creative reservoir. Rice, who had no real musical background, began to write music - songs, waltzes, symphonies. "Something just took over my hands and just played," he tells Cuomo.

"I have very stiff, brittle hands... I got at the piano and I started playing chords and scales and this tune came to me... Then about a month later I wrote another piece, and then I wrote another piece. And it just kept coming." "Primetime Live" airs THURSDAY, JUNE 30 (10:00-11:00 p.m., ET) on the ABC Television Network.

The debilitating effects of Parkinson's lead Rice to undergo a risky surgery -- deep brain stimulation -- that might alleviate his affliction and restore the physical freedom he once enjoyed. But if it was Parkinson's that mysteriously brought him this gift, could a successful surgery cause him to lose his newfound ability and life's passion?

Also: At the age of two, James Leininger of Lafayette, LA, began to have vivid dreams about crashing in an airplane. He also inexplicably seemed to know details about old fighter planes. After doing some research, parents Andrea and Bruce Leininger became convinced that their son had a previous life as James Huston, who was shot down during a mission over the Pacific during World War II. Cuomo reports why some people -- including the dead man's sister -- believe this is a completely plausible explanation for the boy's strange behavior, while others say it's hokum (originally broadcast in April 2004).

And: Just three days after marrying Sean McNulty, Amy Harrison lost her husband to the mysterious world of amnesia. What should have been a joyous time became a nightmare for a young couple who had everything and then, suddenly, saw it all disappear. McNulty became a stranger in his own home, with no memory of his past -- including his love for his wife. He describes to Cuomo how this rare disorder forced him to see the world through a new set of eyes -- until everything changed yet again one fateful day, just before his first wedding anniversary (originally broadcast in November 2003).
