Hi Ray:
I have no reason to doubt the accuracy of Armando's discography regarding the recording date of "You Do Something to Me", as I know he had access to the official recording logs. And, as you point out, the sequence of the matrix numbers should leave no doubt about the order of all four of those recordings.
In my liner notes for the various Sepia Records CDs that You Do Something to Me, Because You're Mine, and The Song Angels Sing appear on, I used the recording dates listed in Armando's book (so, yes, I do trust his accuracy!).
Cheers,
Derek
