Comment by han enderman:
Derby 733 - The tune is Irving Berlin's "Easter Parade", as can be heard on
archive. On the original issue Mitchell a.o. (band members?) claimed "Easter Boogie" as their composition, but after Berlin threatened with legal action (as said on 'rateyourmusic'), the real composer appeared on the label of "Easter Boogie", and subsequently the song title was changed into its original form. So there are 3 versions of the beige/pink label. - In its only Billboard mention (8 Apr 1950, Best-Selling Retail Records), the tune title is "Easter Boogie", confirming that this is the original Derby title. And on the later black label pressing (the last beige label seen is 814), the corrected title and composer are shown. Note that Mitchell recorded more "Boogie" versions of existing tunes, like Derby 739 "Till Tom Boogie".
