Here's a controversial opinion that's come to mind today:
For a long time, I never bothered to get Once in a Livetime because of its bad reputation. I did finally pick it up recently, and I have to say that I think it's a pretty good release. James is spotty at times, but I think the only song that actually sounds bad due to the vocal performance is Voices. There are other songs where he sounds good. The rest of the band is on fire, and there is a lot of good stuff on this release, including some songs that don't really get enough live attention, like Lines in the Sand, Take Away My Pain, Caught in a Web and Peruvian Skies.
It's certainly not their strongest live release, but I don't think it's the travesty it's often made out to be. I think it generally stands up next to the other Portnoy-era live albums, a few strange editing moments or weak vocal parts notwithstanding.
Would love to see a 3CD re-release with the full show (or at least everything but the covers if that's legally problematic), and perhaps some better repair-work on Voices, though I doubt we'll ever see that happen. Looking at setlist.fm, it seems we're missing:
Burning My Soul
Under a Glass Moon
The Way It Used to Be
Anna Lee
Speak to Me
Hey You
Goodbye Yellow Brick Road
Cover My Eyes
and maybe the rest of Scarred, which feels oddly edited here?
