That arrangement sounds like this:
You can see the glass harmonica in the background at 1:13. It's the one that sounds like when you rub the rim of a wine glass. You can most notably hear it, but not see it, during its big moment at 1:55, because the glass harmonica is an obscure instrument and probably the people filming didn't know why this old guy operating a lathe is also in the room with all the attractive kids playing instruments we've heard of.
Usually The Aquarium is performed by an orchestra-sized string section, with glockenspiel substituting for the glass harmonica:
I'd heard stories about an apocryphal recording where the producers wanted to create a performance more authentic to the original arrangement, but accidentally hired "harmonica virtuoso Tommy Reilly" instead of a glass harmonica player. ("Harmonica virtuoso Tommy Reilly" is the only specific ever provided by these stories.) I don't think anyone's ever done the legwork to properly substantiate this story, but the version of The Aquarium on the Burnout Paradise soundtrack sure sounds like it might be the one:
What are the chances that this is a coincidence? That there are multiple recordings of The Aquarium that made this mistake? In my headcanon, it happens all the time. Every night, Tommy Reilly heads into a different recording studio, plays that pair of glissandos, then squawks "it's a living!"
