This is one of my favorite Elvis movie songs. It is from "It Happened at the World's Fair." The little girl he is singing to is Vicki Tiu. In later life, she became the First Lady of Hawaii. Her husband is Ben Cayetano. He was the Governor of Hawaii from 1997-2004.
"Til we meet you again, may God bless you. Adios." - Elvis Presley (Said in 1977 at the end of a concert during his last tour.)
