Do a search for "union jack" and it will turn up a thread on the Can You Brew It? episode on this beer. Alternatively, you can go to the brewing network site and find the podcast. I would link to them for you but I'm on my iPad & it's a pain to copy & paste.
Actually, I just googled "union jack clone" and the first 2 hits are the thread here & the brewing network show. Good luck!
