A plausible, painless package for them:
1 CD - Studio album, probably the Van Dette remaster - plus or minus some kind of bonus tracks, like covers from other artists
2 CD - FtK show from Different Stages, which is OOP, afterall - plus or minus some kind of bonus tracks, like covers from other artists
3 DVD - 5.1 mix, as previously released on DVD-A and BD-A, possibly in DVD-V DTS
@: - "live in studio" promo videos from Chronicles - Closer to the Heart "live in studio" with Bubbles and that guy from the Barenakedladies from R30 Deluxe
If DS disc 3 was already the best FtK show in the vault (and it's not that good - Ged had a cold), I doubt we'll see yet another show appear.
**As for Hemispheres, there are also "live in studio" promo videos they can reissue, as well as live from Pink Pop Festival, maybe. And for Permanent Waves there is the AWESOME SAUCE show from St. Louis that is probably the best performance of their entire career. That show is bat-shit amazing. It was officially recorded and pressed by Anthem records, but only sent to radio stations to promote their tour, never released commercially.**
