Rock veteran Ozzy Osbourne has one big regret about his wild days as a drug and alcohol addict - missing out on the chance to have a "man-to-man conversation" with his beloved father, Jack.
The Prince of Darkness' dad died in 1977 and, in candid new documentary God Bless Ozzy Osbourne, the Black Sabbath frontman admits he was never sober enough to enjoy a real father/son chat with Osbourne, Sr. after finding fame - and it's one mistake he will remember for the rest of his life.
In the film, produced by his son Jack Osbourne, Ozzy says, "I really wanted a man-to-man conversation with my father but I was always on drugs and alcohol... I miss my father."
