Was the song a radio favorite in the 70s as it seems to be now*? If so, it does seem odd they never played it live. When I was younger, I used to think that if you went to see a band, the songs were just chosen in the moment by the band, and the following stop on the tour might have a completely different song list. I still kinda wish live music worked that way.

I only need a few seconds from this song to call it one of Zep's most exciting. That's not to say I don't love the whole thing, but the moment around 4:08 - 4:23 is just one of the most amazing things I've ever heard. Particularly, Page's second lick. It's just one of those astonishing musical moments to me. I've never heard a live version where the band nails this section of the song like they do in the album version (I've never heard Page even try), but I'm hoping that I will someday.

As nice as those audience recordings sound, it's tough to beat a professionally recorded and mixed CD set. I'd buy an official release of that material in a heartbeat. But I'd keep Eddie around because inevitably there'd be some bits that Page would want to edit out of the official release for whatever reason, and I still want to have the full show, with all its quirks.
