So, about the last poll: Only three (four?) of them are really themes, and I think two of them are (fairly obvious) fill-ins. The rest have actual names. :-) However, I didn't actually know that some of these were used as themes, so there's kudos for naming a program even if you can't name the piece!
According to my notes, I don't know the answer to 05:21, perhaps it really is a fourth theme, but I thought I recognised the piece, and I don't think I've ever seen the program in question. But then again, I didn't know it.
I have no idea how to post answers without spoiling it for future visitors.
