I can't say I've listened to the Space Trilogy audio books, but about the "prospect of no CSL" I have the solution to that. Each night when I'm going to sleep I either put on my audio cassettes of the BBC Chronicles of Narnia (film) series which I recorded onto tapes, or else the FotF audio dramas - they're so soothing they help me get to sleep. So I never have the "prospect of no CSL"...and I suppose if I really wanted to, I could put on my CDs of him giving
The Four Loves talks...but I'd really want to concentrate for them!
