This is Part 2 of the session with Willie Robson, which has a somewhat better sound quality as the storm had reduced in strength by the time we had finished lunch. Willie spent an hour answering questions from the audience and I think you will find this session very interesting, especially if you keep or are planning to keep black bees.
I should also mention that I have just published another book, called Balanced Beekeeping II: Managing the Top Bar Hive. It has taken me nearly two years to write and edit and it has 385 pages full of the most useful tips and techniques I know to help you set up, populate and manage a top bar hive. Take a look on my site at biobees.com under books and you will find both paperback and ebook versions.
Willie Robson has written a fascinating book, full of his accumulated wisdom, called, "Reflections on Beekeeping", published by Northern Bee Books. 
Thanks to Graham White for the use of his photo of Willie with an open hive.
