TLFR in general was probably a bit of a failed experiment, as no one seemed to really like it, it wasn't a proper acoustic album but was too rushed to be properly experimental.

That said, I think that a number of the songs are pretty good, each of them offer at least something of interest, and none of them detract from my appreciation of the original songs at all

I saw Always TLFR performed at Milton Keynes 2006 and actually thought it worked quite well in a live setting. Sure, I would have preferred the full electric version, but if it was a choice between getting no version of Always or the TLFR version, the TLFR version wins

Bed Of Roses is a bit different though, because I don't think the new arrangement of that is sufficiently interesting to justify it ... whereas the new version of Always is IMO.

With Runaway (and I can only base this off of the performance on the Crush tour DVD), it was cool because it was a new idea, it was the song that obviously they'd been playing more or less constantly since the very beginning of their career, and probably most of all because it was a one off. I'm not sure it would have worked quite as well with any other song in the entire Jovi catalogue

Here's a slightly different question though: if they were to do different arrangements of rarities and semi-rarities like Die For You, Wild Is The Wind, Stick To Your Guns etc., would that be acceptable?
