Waaaaaaay back in the dark ages before the internet was anything like it is today, the only way to download something was through FTP format. I was using that to download lyrics from the University of Wisconsin at Milwaukee. That later went out of business, and a personal note to the site revealed that the lyrics that were there could be found at a place called Mudcat. If any of you have downloaded from the UWM site, you will notice that the format of many of the songs is exactly the same as the earlier songs on Mudcat. What used to take about 3 to 5 minutes to FTP a set of lyrics at that time takes me about 3 to 5 SECONDS today.
The original UWM site had lyrics for a variety of genre of songs, and "folk music" was just a small segment. I don't know what happened to the other songs that were available.
