Gandalf, #8 (requested by anon)

The Beatles - “Do You Want To Know A Secret” - On Air - Live at the BBC Volume 2
The only sources that I’ve read/listened to that go into a bit more detail on the subject are “Divided Loyalties” by Gary Russell and the BF audio story, “Master" (the latter of which I particularly recommend listening to). I believe "The Dark Path" by David A. McIntee also expands on their personal histories, but I have yet to read it myself.
If anyone else can help the anon out, feel free to chip in.
