Besides a few mailing addresses I found which may or may not be up to date, let Me just leave this up here for Him if He reads these-
left it in comments section too. Love the site.
Dear Mr. Billy Joel:
I just wanted to say this to Billy Joel as a fan for over 10 years- which includes extensive collecting during that time- even though I've known and liked you My whole life. I hope you read this.
I think I speak for myself and others in this comment:
There is nothing for me to gain in anyway by saying that I think your music speaks to everything and everybody in the universe. I don't believe their is a creature or thing created that cannot hear a Billy Joel song and have it move them and relate- and make a lasting impact and impression. There is an advanced intelligence to you and your music- it transends and surpasses time, space, understanding in all realms. It's not just joy you bring- it's wisdom. It brings healing. It tapes into realms unknown. It ignights The Divine Spark of Creation within Us that enables and encourages wisdom, strength, Creativity, Endurance, and Foreverness. You are one of The Chosen Ones whether you believe it or not. The Principalities looked at you in marvel and envy when you were created and The Universe smiled with the loveliness it knew it created that was beautiful in every way, sensitive, intelligent, creative.
A lot of people admire you- but You've tapped into some souls- mine as one- and how you did it I will never understand, but it's like you said: "There are spiritual realms that are not understood- but music tapes into them". You are also very smart as philosopher. You are for sure- someone that will be loved come rain or shine.
