This lot of four DVDs includes a copy of Behind the Makeup, a 1-hour compilation of Doodlebops concert sequences combined with interviews with the cast and improvised scenes. It was never officially released, though the Doodlebops Live In Concert! DVD was based on this. There's some never before seen footage in this one if you look.
The other DVDs, I don't really know what's on them. Based on the labels I'd guess these are the final cuts of the Pledge and Get on the Bus sequences. They were the first dance sequences we shot each season so we could reuse the footage in every episode. The one with the photograph of the Doodlebops performing live at the CBC Atrium could be anyone's guess. It may contain footage of that event but I don't recall.
