Did you ever locate the audio for the Day Of The Daleks omnibus?
I definitely (audio) recorded it at the time, and there's a good chance I still have it.
We do have a copy of the audio for the Day compilation now, but an additional recording of it would always welcome. Sometimes those old 1970s off-air recordings aren't always the clearest and having alternative sources is always a help.
I had been wondering if these missing omnibus compilations would be reconstructed when the appropriate Seasons were done. Your hard work and that of all the others on the team involved in these excellent Blu-ray releases is greatly appreciated!
