Not in many 20s dance band charts; I just played a Georgia Melodians Edison this morning where the last chorus was in F and the last chord was a sudden transition to D flat.

IIRC, a song always (?) resolves to the key on the last note of the piece.  I could be wrong, but it's worked for me.

I'm aware of the advice to listen for certain notes, judge whether they're sharp or flat and adjust accordingly. Which doesn't help as I'm not a trained musician and I don't have a clue. I think I can get pretty close with recordings that have singing or voices, but instrumentals are a real challenge.

I'm currently transferring a large number of my 78s to WAV files in preparation for a radio show I'll be doing at a local college station. So I'm understandably concerned about accuracy. I also have the occasional customer bring old acoustic discs for transfer to digital, so customer needs are a consideration as well.
