I was on youtube and I found some in depth interviews with Patrick and Matthew Labyorteaux and Richard Bull. I'm sure you guys have already seen them, but I found them very entertaining. I thought Patrick's was the most interesting and he told the best stories. He appeared to be a big fan of the show even before he was on it. Richard Bull also told an interesting story about falling off a horse! He has to be in his 80s at least by now but he looked pretty much the same as when he was on Little House.
