For those that might have further interest in the Sacred Steel tradition as played by Tom on this tune here are several links. Although I had seen the Robert Randolph band I was not aware of the connection until several months ago when Tom made me aware of the tradition.

Gospel oriented pedal steel with roots in Florida African-American Pentecostal churches is a perfect example of the richness and diversity of American music traditions.
