Just finished watching Duccio Tessari's 1975 ZORRO, starring Alain Delon as Zorro, Stanley Baker as his enemy Colonel Huerta, and some huge guy simply named Moustache as Sgt. Garcia, and a dog named Assassin that looks like Scooby Doo. The version I saw was the 87 min version, which is quite a bit shorter than the original 124 min one; however, after seeing this version, I'm not so sure it's worth pursuing.
This film is pretty campy, filled with a lot of stilted and bizarre humor, and a title song that sounds like Guido and Maurizio De Angelis, that goes something like, "Here's to you and me / Here's to bein' free / la-la-la-la-la Zorro's Back." As you can see, this is quite a departure from Tessari's other films. There's even a scene that may have inspired Donkey Kong in which Zorro rolls barrels down an incline to thwart his pursuers.
To be honest, the only other Zorro adaptation I have seen is the first Antonio Banderas, so I can't say how it stacks up against the likes of Tyrone Power in THE MARK OF ZORRO.
