Wizard of Oz and various Commentary Tracks

[widescreen forever]

Looking for some information that I can't quite seem to Google properly ...  All the Wizard of Oz releases both from Criterion/ MGM Laser discs as well as the 2005 DVD release I need to know what "authors"  are speaking on these commentary tracks of these 'albums' or video Discs   ...
I think that Ronald Haver might be one (if so which release?) .. and what other people are using their movie knowledge in their own depictions of the entire 1939 Wizard of Oz i nthe Audio commentary section of these various video medias ...  ??

I found that John Fricke did the commentary for the DVD .....
thanks

I have the Blu-ray from 2009. Blu-ray.com described it as below:

Audio Commentary (Disc 1): The late Sydney Pollack hosts this extensive, altogether informative commentary track featuring noted Oz historian and author John Fricke, as well as rare interview clips with associate producer/writer Arthur Freed's daughter, Barbara Freed-Saltzman; actress Margaret Hamilton (the Wicked Witch of the West) and her son Hamilton Meserve; actor Ray Bolger (the Scarecrow); actor Jack Haley (the Tin Man); John and Jane Lahr (children of actor Bert Lahr, the Cowardly Lion himself); uncredited co-director Mervyn LeRoy; assistant choreographer Dona Massin (who worked directly under Bobby Connolly); assistant make-up artist William Tuttle; performer Buddy Ebsen; and one of the last surviving Munchkin actors, Jerry Maren. While Fricke sounds as if he's narrating a documentary -- he's clearly reading from a script -- he lends focus and density to a track that might otherwise be unwieldy and overwhelming. But the real meat of the track lies in its interview clips. Nostalgic reflections, candid anecdotes (particularly from Hamilton and her co-actors), and amusing asides. The audio quality of each clip varies, but such inconsistencies are never a distraction or a detriment. Each voice remains clear and intelligible, allowing listeners to sink in and enjoy everything the participants have to offer.
