The only ones I was not familiar with were the D7b9 & C7b9. I had heard of them but didn't remember the fingering. I guess that they are 7th chords with a flat 9th added ? I cheated and went to a chord web site. I've heard this tune hundreds of times and when I played it for the first time last night (on my acoustic) my wife immediately recognized it and asked "when did you learn that"? When I told her I got it from GT (I had never had an interest in learning it before this thread) she said "get more" !!! Thanks Elmo45; actually my wife thanks you.. BTW, isn't the 1st chord in the verse Fmaj7? I don't know what Fmag7 is.
