I loved Patrick Moraz's contributions to both Yes and the Moodies. I remember being very disappointed when he was no longer in Yes, and thinking at the time he probably wasn't the best match for the Moodies, however he still did well within the less adventurous musical frame of their later period.
I followed the Moraz/Moodies break up at the time and recall Moraz was very unfairly treated by the Moodies and, while he felt he was able to be as creative as he liked with Yes and was free to continue with his solo career at the same time, he felt the Moodies shackled him. The thing that really got to him was that each of the other members was putting out solo albums, but he was not permitted to. I guess there must have been some contractual thing he missed, that meant he was unable to. Or maybe it was just pressure from them not to.
I also recall that Moraz felt he did OK out of the legal action, which found in his favour.
I still love pretty much all of the Moodies albums though, and certainly don't agree with the comment elsewhere that they now come across as juvenile ('juvenilia' was the word used). I believe it's just that the world has moved on so massively since those albums (as it's wont to do), however their musical and conceptual ideas were very fresh and original at the time. Especially To Our Children's Children's Children. At the time, that was mind-blowingly different, pre-dating Hawkwind's space themes by a long mile.
Update: Read below for a different version of events re Moraz suing. All sad really, when this stuff happens.
And I don't think their stuff is dated at all (not that anyone has said that), but some of the music can now have a certain nostalgic quaintness to it (as opposed to juvenile), which for me does not take away from the listening experience one iota. After all, everything looked back on fondly is nostalgic. The world was tough back then as well, but the very act of looking back can make things seem quaint now.
