My mother had been at the 2004 Edinburgh Military Tattoo and had gotten a VCR cassette. They don't hold up over time so we were on the hunt for a CD version. Found out the producers never sold it as a CD. Tried to get a copy made and couldn't because it's copyrighted. After viewing the 2007 one, we were pleased with the quality and content. Very similar to the 2004. Glad we got it.
