On speaking to Gene Doucette last year it may or not be common Knowledge but the story goes that the Pheonix suit was originally called the Jungle suit, the design was meant to be two Zebra heads meeting in the middle and with the stripey belt the same as zebra skin,
Elvis walked into Genes shop when he was making it and was looking at the design upside down and said "what a funny looking bird " well not willing to offend the king ,(sounds a bit like the old fable the kings altogether). they came up with the phoenix by adding the feet and beak,
take a look at the suit upside down and you will see.
this has probably already been talked about , let me know if its the first time its been heard.
