It's still available if anyone is interested.

Anyway the part that I thought was interesting is this bit:
The two new songs are "Rev" (with Tom Morello and John Frusciante on guitars).
Initially recorded for but not included on 1997's Kettle Whistle,

I seem to remember hearing the band had worked on other tracks while recording for Kettle Whistle but up to now don't remember ever hearing that one of those songs was Rev.
Maybe this is old news and I just missed it somehow.
Does anyone else have any info on this?
