This is the title we assign to the blues done by Roger "Jellyroll" Troy on 7/2/74 with Jerry and Merl at the Bottom Line. It is not the same as LeRoy Carr’s “How Long Blues", which is how it was historically listed. It shares a bridge with “Don’t Want No Woman,” the “you drink your whiskey” section, as recorded by Magic Sam + Bobby Blue Bland (separately) in 1957. It could just be the 'roll improvising, so we list it as "How Long" for now to maintain some continuity with historical listings. Thanks to Jesse Jarnow and Caleb Kennedy for their help with this.
