If you are interested in learning about Graceland I encourage you to seek out the wonderful books authored by Alanna Nash (available on Amazon.com). Additionally these books are not only a must have, for all Elvis fans, but factually based and underscores the ups and downs while being balanced. It is a rare combination indeed.
Also for “insider info”, for what occurred during Elvis’ life there, please search and support; Marty Lacker Billy Smith, Sonny West, Red West, Joe Esposito, and Jerry Schilling.
Take care and may God bless you.
