I've been trying to recall the name of Singing Hills for over a year now. I didn't see it on RVParkReviews before we went up there this summer. We stayed there several years ago and yes it's basic but it does have FHU. The pond was a major hit with my son who was actually catching fish in it. He also caught a big snapping turtle which the owner removed.
We have over nighted there several times on our journey South. It is a basic c.g. but the pull thru sites are long and the owners very friendly and eager to help.  We never use c.g. washrooms, but years ago I took a look and was not impressed.  Maybe washrooms have been upgraded since then, I haven't been in them for about 5 years.  If really modern washrooms are important to you, you might want to check this out.  With full hookups, your own facilities would probably be used anyhow. 
The park is only a few miles from Mammoth Caves.  Between the interstate and Singing Hills, there are lots of tourist traps to take your money.
