When did James start using the 12-string for Fade To Black?

I'm trying to find what the first show where James used the 12-string for Fade to black was. Anyone wanna help me?
I had no idea until today that he had used it earlier than '93-'94.
Sometime in 1992 he started using it.
The earliest video I can find of him using it during a show is of the Mobile, AL show on June 14:


On May 30 in Anchorage, AK he still played it on a 6-string:
