It Happened at the World's Fair is the sixth soundtrack album by American singer and musician Elvis Presley, released by RCA Victor in mono and stereo, LPM/LSP 2697, in April 1963.

[4] All three of these songs, "I'm Falling In Love Tonight", "They Remind Me Too Much of You", and "One Broken Heart for Sale", would be included on the 1995 compilation CD Command Performances: The Essential 60s Masters II.

[5] "One Broken Heart for Sale" and "They Remind Me Too Much of You" would be released ahead of time on January 29 as a single to promote both the album and the film.

[8] Originally a deluxe-priced gatefold sleeve album was planned, but with only 21 minutes of music and the relative failure of "One Broken Heart For Sale" the idea was abandoned.

[10] In 2003 It Happened at the World's Fair was reissued on the Follow That Dream edition that contained the original album along with numerous alternate takes.
