Katzmanatin' Rhythm - Slide instrumental in open D tuning

I learned this one from Nick Katzman's cd called "Prevailing Winds From The South"
What challenged me to learn this one is the use of a "triple" thumb, instead of the already difficult 'double thumb'

Nick Katzman is a legendary guitarist who recorded two influential albums for Kicking Mule.

TAB for this song is on the cd "Prevailing Winds....". There's a pdf file with three tabs on it.

I'm playing a mahogany 1927 Supertone "Lindbergh" model.
