Dear Ms. Beeson,
Thank you for posting your request on History Hub!
We searched online and located the article The Dodge City Cowboy Band by Clifford P. Westermeier on the website of the Kansas Historical Society which references the performance of the band at the inauguration and provides a citation.
Another potential source of information is newspaper articles from the time period, particularly those for Kansas newspapers and Washington, DC newspapers. We suggest that you use the Library of Congress website Chronicling America: Historic American Newspapers for information about locating historical newspapers.
We hope this is helpful. Best of luck with your research!
