Doug,
Thank you for your posting. I loved one of those albums of yours. My older brother must have had one of your albums - long gone - and I played it alot through the mid-70s. Along with Here's to Your Rounders, I learned to play a song that I think was from your duo - I never knew the title, but I call it Aunt Nora. The chours includes the lines 'She was 80 and I was 13' and 'Oh darkies how my heart grows weary for Aunt Nora and the old folks at home.' I guess I am just wondering whether that was indeed from Freeman and Lange or elsewhere. If its yours, know that it has been loved to death for 4o years now. I play it at campfires and for the kids and when I get lonely for the Aunt Noras of my own life. Since I figured it out when I was about 14, I doubt my chord progression is right :)
All the best -
