That's the dub that Titra did for the US release. The dub on the Sony DVD is the bland international dub that was done in Hong Kong. Titra also did the dubs for the US versions of
Mothra vs. Godzilla,
Godzilla vs. the Sea Monster,
Destroy All Monsters,
Godzilla vs. Hedorah, and the
Ultraman TV series (among other things, I'm sure). The Hong Kong team that did the international dub for
Son of Godzilla also did the international dubs for
Godzilla vs. the Sea Monster and
Destroy All Monsters, which can be heard on the Sony and ADV DVDs, respectively.
It is interesting that your Anchor Bay box set has
Son of Godzilla included in it and featured on the box art. I have the box set myself but mine had
Godzilla vs. Megalon included instead. I bought
Son of Godzilla separately.
Here's another
Son of Godzilla VHS with the Titra dub:
Also, someone on Tokyo Monsters posted pics a while ago of an Anchor Bay
Godzilla vs. the Sea Monster VHS with matching box art as these other releases. Apparently it was included in another version of that box set in place of
Ghidorah The Three-Headed Monster. Here's what they posted:
Here's a VHS of
Godzilla vs. the Sea Monster released by Goodtimes which featured the Titra dub:
Hope the back of the box doesn't spoil the movie for anybody:
