Larry, For "Crazy" I prefer the 12-8 Ballad, "A" variation, tempo of 72 and play my own intro. At the bridge I switch to the "C" variation and sing that part in two-part harmony using the Harmony-M.
For Walking After Midnight I use the Country Swing style, tempo of 100, "B" variation, second intro.
Cheers,
Gary
