@slaw Indeed, Cafe' Blue is on my list for tonight. That album and on the 1-Step production, is sure to tell it all.
@gmercer the Zeppelin album at MSG brings this to mind for me. I forget the name of the album, but it's a 3 disc set, live album, that was recorded over 2 nights in 1973. Is that the album you have? One of those two nights that went into the recording was at the Fabulous Forum in Inglewood, CA. I was at that concert!!! Maybe the other night of the recording was at MSG. What memories...
