Spot on Brian, a bit more info:
This is about a brothel in New Orleans. "The House Of The Rising Sun" was named after Madame Marianne LeSoleil Levant (which means "Rising Sun" in French) and was open for business from 1862 (occupation by Union troops) until 1874, when it was closed due to complaints by neighbors. It was located at 826-830 St. Louis St.
The melody is a traditional English ballad, but the song became popular as an African-American Folk song. It was recorded by Texas Alexander in the 1920s, then by a number of other artists including Leadbelly, Woody Guthrie, Josh White and later Nina Simeone.
It was her version The Animals first heard. No one can claim rights to the song, meaning it can be recorded and sold royalty-free. Many bands recorded versions of this after it became a hit for The Animals. (Thanks to Ron Foster for above 2. More from Ron at
