Father sings 'Blackbird' to dying newborn son just days after wife passes away

He says over the course of two days, he sat and played and cried and sang at Lennon's side. It was a friend to took the video of Picco gently playing "Blackbird."

"It's a song I really love and I was looking to play songs that had kind of that melodic movement that might trigger something in him," Picco said.

It was also a song that as a Beatles fan, Picco hoped he would be able to play for Lennon as he grew up.

Picco and his wife had decided to name their son Lennon before she died.

"We both share a love for music," he said, laughing a bit as he spoke. "It kind of spoke to that musical element and also we didn't want, we were kind of looking for that little bit of uniqueness as well, but we didn't want to go too crazy like naming our baby after a fruit or vegetable or something."

A memorial service for Ashley and Lennon is being held this weekend in Southern California, where the family lives. A fund to cover the family's expenses has already raised over $60,000.
