That's what it's all about, KC- working a partial, or as you say, "faked", chord into the song. Pros do it constantly. When it comes to playing songs you love, there are no rules. Those chords are really valuable. Sometimes, for the effect, other times for pure simple laziness. Often for both reasons at the same time.
I just read Max's thread about the upcoming Mudcat Concert. I really hope they are able to archive that, as well. If none of this has been done, maybe I can give a listen to the tapes you, Kat, et al have put together.
A lot of my favorite music is stuff I recorded live off of the radio, from simulcast concerts. This music is now gone, unavailable on any CD. Versions of the various groups appeared on albums, but it's not the same, especially the between song banter. Somebody probably has master tapes, but I doubt if they are available.
I guess the moral is that the music being recorded, (hopefully), now is precious, and will only increase in value in the future. Get it while you can, and ENJOY. thanks, BlueJay
