Will do Wardy, not discrediting neither MS nor TC so perhaps my words were a bit harsh - just the way I remember them compared to the ones I appreciate the most is considerably weaker than the first 4.
A think that IMO came gradually, album by album after those stellar first four albums.

In fact KC only has a few albums I don't have much, if any love at all for is Perpetual, Ain't Crying For The Moon and Too (re-recordings killed the last one mentioned for me). In regards to BI the fact that is less Zep-ism is one of the things that appeals to me, as strange as that may sound when my fave album of theirs is the debut and I love Zeppelin too.

But yeah, I'll dig it out and try to listen to it with fresh ears. Thanks for the heads up
