Lost Footage Shows John Lennon Months Before Death

INSIDE EDITION takes a look at some lost footage of John Lennon on the 30th anniversary of his death.

It's lost footage of music legend John Lennon.

It was the summer of 1980 and Lennon was preparing for his big comeback.  Five years earlier his son Sean was born and Lennon and Yoko Ono decided to take a break from the music world to raise their son.  Now it was time to get back to work and Lennon was preparing songs for what would become his final album, Double Fantasy.  
 
The song he's performing in the lost footage is called "Dear Yoko," and it's a heartfelt love letter to his wife.

Lennon, who changed the world as a Beatle, was making the simple video all by himself. He was out in his getaway home in Long Island's Cold Spring Harbor where he set up a home video camera, pressed record, and started a rough performance of his new song. Just 5 months after he made the video, Lennon was killed by a crazed fan. He was only 40 years old.

"No pulse. No blood pressure. No spontaneous respirations. He was totally unresponsive," said Dr. Stephan Lynn, the ER doctor who tried to save Lennon's life.

"I held his heart in my hand, I massaged it, but in spite of all of those efforts, I pronounced him dead," he said.

It was Dr. Lynn who announced to the world that Lennon was dead. He still remembers what he said that night, almost word for word.

It's hard to believe Lennon has been gone for thirty years. Now this lost footage stands as a testament to a music superstar focused on his family, not knowing his life would be tragically cut short.
