I've encountered a problem regarding Sonny Boy Williamson(s). It seems as though most people either don't know that there were two of them or they're simply don't care enough to acknowledge that there were two of them. The problem is I now don't know who I'm listening to. If you know which Sonny Boy did the following song (if either, it's a P2P program and some ridiculous stuff comes them) could you tell me?

Help Me
Good Morning, Little Schoolgirl
War Time Blues
Mississippi Delta Blues
Steady Rollin' Man
Cross My Heart
Nine Below Zero
One Way Out
Baby, Don't Worry
Highway 69
