Billy Murray, known as "The Denver Nightingale," was one of the most popular singers of the early twentieth century. It's estimated that he recorded from 6000 to 10,000 songs over a forty-five year career. Here's his 1906 recording of "You're a Grand Old Rag" -- soon to be changed to "You're a Grand Old Flag." (It took a while to find this particular one on Youtube -- most of the 1906 Youtube clips start with an ad from Lara "Mrs. Waste of Protoplasm" Trump, aka Mrs. Eric Trump, in which she co-opts the song to shill for her father-in-law. Ptah!)
Enjoy this Trump-less version.
And have a happy and meaningful holiday.
