Elvis had a small party at Graceland with food provided by Monty's Catering. Sometime over this period of Christmas time Elvis tried LSD. He had read about it for almost a year and wanted to try it himself. Afterwards they watched a SF movie and ordered pizza. Later Elvis, Larry, Priscilla and Jerry walked out behind Graceland and talked about having such good friends and how much they all cared about each other. As for anybody knows this was the only time Elvis experienced with LSD.
