I have known about this score for some time, but just recently found it digitized and placed on the internet at the Indiana Historical Society. It is amazing what a google search will turn up.
The "Dan Patch Two-Step" was published by the International Stock Food Company in Minneapolis in the early 1900s. Dan Patch was a world famous race horse and the song was written in his honor.
I'm still trying to find out who H. G. Trautvetter was. I do not think he is a member of "my" Trautvetter/Troutfetter family which settled in Hancock County, Illinois, and who were descendants of Erasmus and Anna Gross Trautvetter of Thuringen, Germany. I'm of the mind that all the Trautvetters are related, it is just a matter of making the connections.
Maybe I'll get someone to play the song and we'll place the tune on on the site.
