Houston-area demolitions: Were you involved in removal of Sea Arama Marineworld or the Mary Moody Northen Amphitheater in Galveston?

Being an older Houston-area guy, who grew up in Galveston, I was just doing some reminiscing while checking some Google Satellite imagery.

I worked at both of the places in the title, and when they were active, there were some substantial structures.

Google Maps still shows "Mary Moody Northen Amphitheater" but satellite view shows nothing remaining of the theater itself.

Demolition of both of these places had to be pretty significant tasks.

For instance, the stage and seating areas of the amphitheater were concrete. Must have taken a lot of jackhammering and bull dozing, etc. But before that, they had to remove the booth at the top where lighting and sound were controlled. On the roof of that building were follow-spot placements. The spotlights there actually used carbon rods and the light came from an intense electrical arc. I remember hearing the buzz and seeing the smoke.

I wonder if those old follow-spots have been saved, or if they ended up in pieces in a land fill.

If anyone here was involved in any way, I hope we'll have some discussion.

If you were NOT involved in the demolition, how about sharing any memories you have of attending either tourist attraction? (Of course, you'll be revealing that you're not one of the younger redditors here…)

Edit: There are a lot of videos on YouTube that show some of the history. Here's one.
