Hi Leon: Though I've admittedly seen this tune shown (incorrectly ) in some charts as in 3/4, it's actually imo a 4/4 blues tune (with a 6/8 feel) as evidenced by it's classic guitar appegio line: http://www.eskimo.com/~ogre/print/beginner/20010513.html

To add to MacAllcock's contributions, here are a few more 3/4 country waltz time chestnuts:

Amazing Grace
Cattle Call - Eddy Arnold & Scott Yee
Four Walls - Jim Reeves
Satisfied Mind - Porter Wagoner
I'm So Lonesome I Could Cry - Hank Williams Sr.
