Ace Bourke and John Rendall are preparing to leave on a book publicity tour for the launch of the revised book A Lion Called Christian. The two will be travelling across America and the UK in the coming weeks to promote the book based around the lion cub they purchased from Harrods and released, with the help of George Adamson, back into the wilds of Africa.

The updated book details their reunion with Christian in 1971, as seen in the widely popular YouTube clip.
