Jerry,
I thought you would know that saying!

This is how I figured it's meaning out..not saying that it's the right meaning but it works for me:

If you have lost some of your mental ability while you were sleeping, then your mind would not be fully clothed, or you would be clothed in your 'wrong' mind and not the one that you had before
{which is your 'right' mind} 'right' here being the same as 'whole' or 'correct' {fully functioning}.

BTW, Jerry, thanks for the link to your song..I'd love to hear it sung.

And speaking of that..I can well imagine the "beautiful night the Gospel Messengers and Shoregrass had last Saturday. It was a joyful time, and "rejoice" is just the right reaction to have. Saying we had a "good" time doesn't cut it."

One of these days I'd love to hear your group because I know I'd be rejoicing right along with others there.
