Presley was pulled over for speeding on Christmas Eve, 1954; in 1971, he spent that day in his podiatrist's office.
On Christmas 1958, Elvis sang his Army buddies a version of "Silent Night" as they put up the Company tree. That same year, his manager, Col. Tom Parker, sent to members of the Elvis fan club a card with a picture of Elvis in his Army uniform (and Parker dressed as Santa Claus).
Priscilla's first Christmas present to Elvis, in 1959, was a set of bongo drums. Three years later, she gave him a cigarette box that played the tune to "Surrender."
Elvis always said his favorite Christmas gift from his entourage was a leather-bound Bible. They also gave him a statue of Jesus, which still stands in the Meditation Garden at Graceland.
"If Every Day Was Like Christmas" (1966), the last holiday single Elvis ever released, was written by a childhood friend, Red West.
In December, 1970, after his father, Vernon, and his wife, Priscilla, confronted Presley over his spending on gifts, he made a spur-of-the-moment trip to Washington, D.C., where he would meet the president. The event was immortalized in the 1997 cult film "Elvis Meets Nixon."
