It is difficult being the son of a legend, more so if your father is a true icon and you just happen to share the same name. For Frank Sinatra Jr, it was a little bit of the best of both worlds. His name opened many doors but it also brought stress and even got him kidnapped. Still, Sinatra Jr could claim to have the coolest dad ever and, by his own words, Frank Sr. was a good father. Now, Frank Jr. gets to join up again with his father in heaven. He died yesterday at the age of 72 of an apparent heart attack.
