I don't have a book right now to read to them...so they listen to this instead. I have literally TONS of MP3 radio shows too, from the 30s-60s!
You got to love all those classic shows. They don't make them like they use to. Heck they hardly make them at all.
Have you checked out the "Redwall" series by Brian Jacques? I'll bet both boy would love the stories of the good animals (mice, moles, voles, badgers, hares )fighting to protect themselves from the bad ones (weasels, stoats, rats). Pick up one of them next time you're at the library. Start with "Redwall" or "Martin the Warrior"
