The reunion of the lion and the two men who raised him happened 35 years ago. The two men, John Rendall and Ace Bourke purchased the cub in 1969 in London when the sale of exotic animals was still legal. After the cub, newly named Christian, grew from a mere 35 pounds to 185 pounds his caretakers tried to introduce him to the wild in Africa where he was successfully fully integrated.
A year later, Christian's caretakers flew to Africa to see him and the result of that reunion may be seen in this clip now made popular by YouTube.
Rendall and Bourke hope that their story will help awareness of wild life conservation.
