The notes to the Sepia CD, Through the Years - vol. 8 state:
JOSEPH J. LILLEY AND HIS ORCHESTRA, CHORUS
TRACK 13 – Blue Skies / I’d Rather See a Minstrel Show / Mandy (Berlin) (with Danny Kaye)
The date of September 9 quoted in the Decca logs for this track must be a mastering date as Bing was still in Idaho. It may well be that the track was recorded on April 10, 1954 when other songs from White Christmas were laid down. To confuse the position further, the master number is a New York integer and the earlier songs were recorded in Los Angeles.  However, when comparing the similarity of the recordings done for the actual film with this track, it seems possible that this was a composite medley edited together from the soundtrack recordings in order to complete the Selections from Irving Berlin's “White Christmas” album. After all this confusion though, the outcome is that Bing and Danny Kaye give competent versions of three of the songs from the film. The album was issued in the U.S. as a 12-inch LP, a boxed set of three EPs as well as an album of five 78rpm discs. For this last mentioned set, the three songs were too long for a 78, so “Blue Skies” was edited out leaving “Minstrel Show/Mandy” with a new master number – W86945 – and a mastering date of October 19, 1954. For reasons unclear, the “Minstrel show” title never appeared on any record labels or track listings.
