What was the B-side to “The Night the Lights Went Out in Georgia”? Seriously. 
According to this site, the B side to “The Night the Lights Went Out in Georgia”, the 1972 Vicki Lawrence 45, is “Dime a Dance”.
Yup. I actually had this record. This was one of those occasions where I liked the B side better than the single, in fact. That said, I don’t remember a thing about the song other than that I liked it and it was about a dime-a-dance girl.
