Not that it's any help, but I've actually seen two different ladies playing the drums at the saloon. So it could be a couple of different people.
You might want to try asking on the SDC Fans facebook page, or even on the "You Know You're from Silver Dollar City" facebook page (you'll have to ask to join that group, but they let in anyone who isn't a spammer) More people will likely see your post there and perhaps be able to give you an answer.
