== Yellowcake UF6 == 

 Two things regarding "Yellowcake UF6": 
 *The title is two references to uranium refining: see Yellowcake and Uranium hexafluoride. 
 *Some (all?) CDs in the UK (other places?) incorrectly give the title as "Yellowcake UFO". This is probably caused by somebody at the record company not being aware of the above.
