The one about the World's Fair in Seattle, right? As I recall, she has a good dance routine near the beginning of the movie . . . .
You've just won the Christmas Turkey! A quick search reveals that Yvonne starred in roles with Elvis Presley in two films:
"It Happened at the World's Fair" and "Kissin' Cousins."
Celeste Yarnall starred in the Elvis Presley vehicle:
"Live a Little, Love a Little"
I tried to watch the World's Fair one, mainly because I attended the same World's Fair as a child, but couldn't get through it. Yvonne is cute in the dance number, though.
