Thanks all for your nice comments
Thanks Tony, regarding the face, whenever I miss, the ugly face wants to come to the surface. It is a battle to stay cool. When I play golf sometimes I feel like a hammer thrower with my golf clubs, but with the guitar it is a bit more delicate. Seriously, I like those oddballs songs.
Thanks Bob, it is really fun to play especially the 2 slides on the fat string give some punch to the song.
Thanks Mark, One way of selecting those songs for me was to look for finger picking songs on you tube and over the internet and select the one I like, so this is why they might not be the most well known, but they are interesting.
Thanks Beaker, like any of the song that we decide to learn, if you are motivated by it , you will go through. From what I saw, you sure can play this one.
Merci Pierre, I have been working on this for about a year and a half. It seems like a long time but I find that it takes a while for the fingers to remember what to do because the strings are never in the same order for each chord in a given phrase. I found a Guitar Pro file which seems close to what I have seen played on you tube.
Thank you Michele, I love this song. I think the playing looking comfortable is due to Neil constant reminder of the hands position that is starting to sink in (do not have to remind myself all the time, it is getting more automatic), As with the other alternate tunings,as you know, the frequency of practicing a song that you have to re tune the guitar is lower unless you have a few in the same tuning. I also have been practicing Friends , also from Led Zep which has the same tuning. So at least when you are tired of one you can do the other one. It was the same thing with Black Mountain side and Kashmir which are bot DAD GAD.
Thanks Jason, as mentioned above it was a guitar Pro file that I followed. Regarding the strap my Molson muscle might help a bit

, but if the orientation of the fretboard is closer to horizontal it will slip. So being a little higher helps, as if I let go my two hands , it will not move. The benefit to hold it higher also helps with the wrist, since it does not have to bend as it is straight with the forearm, reducing the baseball bat grip temptation.
