This might be one of the most difficult videos to get through without crying ever. <br /> <br />Musician Chris Picco was recently filmed gently singing the Beatles song Blackbird to his three-day-old baby, the aptly named Lennon. <br /> <br />Lennon’s birth just 72 hours before was a complicated one, and his mother Ashley sadly died after giving birth to him. <br /> <br />Hours after Chris serenaded his son, baby Lennon also passed away. <br /> <br />The video of one of the last intimate moments between the father and son was uploaded to Youtube by a friend where it instantly went viral. <br /> <br />A memorial fund was also set up following the tragic event to cover Chris’ expenses <br />Chris posted a heartfelt message to the memorial page thanking his friends and family for their support and paying tribute to his wife and son. <br /> <br />‘I am so thankful for the four unforgettable days I got to spend with him. His mommy would have been so beyond joy to see him and to hold him, touch him, bathe him, sing to him – as I have had the privilege of doing,’ he said.
