So we had 35 demos for Td. Do we have all of them as b-sides or as songs on box-set??

I tkink that we have it all because they had only vocals and guitar recorded for "letter to friend" and them recorded rest for final song which they put on box-set.
I don't think that they would record songs like letter to finish them if they have more full demos. But they probably have many demos of songs which finally make record.

Wait, are you saying the drums bass and keyboard were added in 2004?

Not sure if Letter and Only In My Dreams count in the tally. And there are a couple I've queried too.

These ones seem really off to me. I Get a Rush has to be post TD, Pre Crush, I wouldn't believe it was for These Days.

Someday Just Might Be Tonight would be for Crush.

I'm pretty sure "WaYD?" is from Keep the Faith.

Yes. Some demos were unfinished and they add some guitar, drums, bass ecc to make them complete. "Letter" has only vocals and guitar or drums. I don't remember which one for sure. In videos from box-set or other on youtube you can see them in studio record some stuff for box-set. I remember video where Jon play on acoustic gitar which they add to unfinished demo.

It was I Get a Rush they added, at the very least, the acoustic guitars. Pedal steel to River Runs Dry too. Where did you hear/see/read that Letter only had vocals and guitar?

That's one thing I like about the boxset, they all sound like finished songs. Some even have a pretty good production. If there's another boxset, they should review all the songs and make it a consistent release, and not just put a bunch of demos together.

In 99% it was in interview with Obie about working on box-set. I will try to find it but now I think that it will be hard to find.

Yeah, it's pretty obvious that some songs were re-worked before the box set release.

Always is another example. It doesn't sound like a demo at all. They just took the vocals from 1995 and added all the instruments in 2004.
