My dad took me to see the Firm in Dayton, Ohio. I was 15 at the time and it was a great show. I still listen to the 2 albums from time to time, but agree, Page's collaboration with Coverdale was more Zeppelinish, and I think Jimmy was in better health after kicking his habits. It's a shame that ticket sales were lack-luster for what was gonna be the North American Coverdale/Page tour.
I have a Roy Harper disc from around the time the Firm were making the first album that has a few track with Page that are pretty good.
