Seems to me like that audio clip of Santa would have scared the daylights out of little kids back then and even now. He sounds like a deranged man.
The clip and more vintage Christmas musings is actually available on CD.
Voices of Christmast Past CD
23 original vintage recordings from 1898 to 1922 featuring the voices of recording pioneers: Cal Stewart, Henry Burr, Harry MacDonough, John McCormack, Haydn Quartet and many more!
I have this in my collection and highly recommend it for the Christmas history associated with these old gems. One of the tracks similar to the one above is "Uncle Josh Plays Santa Claus" - by Cal Stewart. One gets a glimpse of the Spirit of Christmas that existed back during the time period.
