Comment by han enderman:
Par R-1110 - composer A is E. Di Capua, as shown on the first edition of the
sheet music and on (linked)
Par DP 87. Often written as E. di Capua, the spelling 'E. d. Capua' on the label looks like an error or misinterpretation and I doubt if this small 'd.' should become a capital 'D.' in the track details (to be corrected?). - Having written this, I now see that the orig. issue
Odeon 11588 by Wiener Bohème-Orchester gives the composer as 'E. d. Capua'.
