Grab your hankies, people. A video of a father singing to his son is quickly turning viral. Chris Picco's wife, Ashley, died following an emergency c-section last week in California. A friend taped him singing "Blackbird" by The Beatles, to his premature son Lennon and it's just beautiful. Sadly, little baby Lennon passed away yesterday after being delivered at only 24 weeks old. You can view a memorial page for the mother and son here.
