Hi, I'm not sure if this is the right place to post, but I am doing some jug band research and have a question. Does anyone have any sources about jug bands or the jug being used in minstrel shows from the early 20th century (between 1900 - 1915, before the recordings of the 1920s)? In other blogs and forums, I keep seeing that jug bands were popular in minstrelsy but can't actually find any sources. I know Gus Cannon was active in travelling medicine shows, but that's about all I can find.
