Really, thanks for noticing! That was part of the challenge, and began this about a year ago, just bc the guitar work was so fun. Then I began constructing a bit more so the arrangement "fit". Tried open G, open D, then open C was the winner. Steemit was is the catalyst for pushing this version out. So thankful for the sake of my battle with the creative process. I tried finding a solo version (as it's not the best/popular zep song) and couldn't find one so what the hey!
