I don't have a Roland, but a nice variation on the Slow Swing style would be a 6/8 Slow Rock at about 70 BPM...I use it to play it in Floyd Cramer fashion.

A 16 Beat Ballad will work nicely as well, and give a more contemporary sound...60 BPM is about right, and using a Rhodes style Electric Piano for the melody really adds to the effect .

Never tried chestnuts roasted on an open fire...prefer turkey roasted in the oven.
