Lead Belly was definitely one of greats on the 12-string, Eric, which he demonstrates on his version of "The Gallis Pole." For anyone who's not heard Lead Belly's take on this traditional song, check it out here. Jimmy Page does indeed take a cue from Lead Belly, playing the 12-string on Zeppelin's version of the song, which they renamed "Gallows Pole." Here's a clip of Plant and Page playing the song live.

Glad you liked the article, Eric and Jamieson. Thanks to both of you for your comments.
