Haha the lady thought she had a free parrot. I once found a donkey wandering about in the back lanes. I couldn't work out which field he had come out of. I made a temporary halter out of a tow rope and was wondering how I was going to fit him in the back of the Volvo saloon when his owner rocked up in a Land Rover. I had mixed emotions, I would have loved to take him home despite having nowhere to keep him but was very glad that he was back with his rightful owner.
I think Casper, like Kiwi, knows he is in a pretty cushy roost here, especially after his last gig, and isn't going to let us out of his sight.
