The Wonderful Wizard of Oz Omnibus 3 (Doctor Who time tunnel effect)

'Ozma of Oz' was the 3rd of 4 instalements in the omnibus version of 'The Wonderful Wizard of Oz'. First broadcast on First Choice, Canada, 1987.11.03 This omnibus includes the time tunnel scene from Episode 31. The audio is not identical to the episodic version. It seems they made the omnibus version using the separate audio elements (rather than cutting down the finished episodic version). The time tunnel scenes from Episode 44 were omitted from the omnibus format.
