Ben Aaronovitch in an old pre-Lost Stories interview (paraphrasing) said if Earth Aid had happened, his planned TNG-pastiche opening would have been on a 1990 BBC budget and likely looked terrible, so maybe it was a good thing it didn't happen! So if fans are complaining the audios don't seem like the old 27 Up plans we built up in our heads, well, neither could the eps if they ever happened
(God knows what Night Thoughts would've been like, no way on God's green Earth is the BBC letting a story as gruesome as the audio out for the kids)
