This question made me think of something that happened about 50 years ago when I was a boy.
At a revival meeting in a Southern Baptist church my aunt who was about 40 something at the time was moved to go down at the alter call and accept Christ.
My grandmother (her mother) a very reserved lady of about 80 years old was there as well. Upon my Aunt going down and wanting to be saved something happened. My grandmother stood and began a sort of shouting/singing and stepped into the aisle and did some sort of dance like a form of clogging all the way to the alter where my aunt and the preacher were.
Never saw her do anything like that before or again.
