These stupid celebrities have nothing to do with nothing. Most of them will be broke and in debt the day after they stop producing top 40 songs. Real power brokers don't use stupid hand signals or flap their gums about being involved in secret societies. Their symbolism is much more subtle... a single red rose for example or an obelisk or other Isis/Osiris/Horus mythology symbolism.
Bill Cooper's "Mystery Babylon" series (from his radio show...can be found on youtube or HOTT website) is a good primer on the subject, his book is great as well. Scarlet and the Beast by John Daniel is a very thorough book on the subject of secret societies and their histories. Take his prophecy interpretations with a grain of salt, but otherwise the history is well researched and sourced.
