Hi Mike
You could try the Waltz Ballad in the March & Waltz section played around 140ish.
However, I tend to use Rock Ballad in the Ballad section at 70. It gives it more of an arpeggio backing, but from a tempo point of view the strong beats fall on the
1st & 3rd beats, which takes a little more getting used to. Give them both a try
