Friend's death inspired Elton John's bid to be a father

Elton John was inspired to become a father after the sudden death of his friend.

The 'Rocket Man' singer - who, along with husband David Furnish, celebrated the birth of son Zachary Jackson Levon Furnish-John on Christmas Day via a surrogate mother - had previously resisted Furnish's pleas for them to start a family together, but changed his mind after musician Guy Babylon died of a heart attack in September 2009.
