Thanks for spotting the mistake. It seems, however, that the cat# is correct but the label images, later added not by the original contributor but by another member, don't belong here.
These sides with Max Terr's Mixed Chorus and John Scott Trotter & Orchestra were on Decca 18510 when first released in October 1942, see review in the Billboard magazine of Oct 17, 1942, p. 65. (Actually the same coupling of Crosby songs was earlier on Decca 621, but with Victor Young and His Orchestra and backing vocals by the Guardsmen Quartette.) This record was also included with the same number (18510) in Bing Crosby's 1945 album set Merry Christmas (Decca A-403), as said in the record notes.
The 1947 album issue of Merry Christmas (Decca A-550) consisted of the same four 78 rpm records, but two of the eight songs were remakes, one of them “Silent Night”. This 1947 remake and “Adeste Fideles” were coupled again on one record, but it now had cat# 23777, see Wikipedia.
Thus these images have to be moved to a newly created entry of the record.
