Remember the Alamo?

In 1982, something happened at the Alamo that instantly became both Rock & Rock lore and a bold question mark in the Osbourne family history. So, nearly 35 years later, Jack and his dad head back to the "scene of the crime" (against Ozzy's wishes and warnings) in an attempt to uncover the truth and hopefully rewrite history. Along the way the guys take a couple of detours, including NASA's Johnson Space Center, where they test drive the new Mars Rover, and a stop at the Museum of Funeral History.
