I'm not familiar with LZ's version of Travelin' Riverside, but if it bears any semblance to Robert Johnson's it should be noted in passing that RJ lifted the main guitar lick in that from a 1928 or '29 recording of Hambone Willie Newbern's Roll and Tumble. RJ also used the same basic lick for If I Had Possession Over Judgment Day.

A few days ago, after spending hours working out an arrangement of When The Levee Breaks from the Kansas Joe McCoy/Memphis Minnie version, I found out it was a "Led Zeppelin song" and their version is revered for a seminal drum line. Ruined my day! Then I listened to it and felt their version was so far from the original that it didn't make much difference.
