I presume the radio sessions will be those previously released as part of BBC The Archive Series CDs.
As far as I know the only live recording of tracks from the album are from a gig at the Birmingham Polytechnic, which was broadcast on Janice Longs Radio 6 Show a few years back. There could well be other live recordings in the vaults.
I seem to recall that Neol Davies mentioned there were a few demos recorded after Pauline Black left. It would be great if these could see the light of day. He also mentioned that he has a demo tape of the Transposed Men sitting on the shelf.
