What's Billy Joel doing in Middletown?

He was filming the hit 1993 music video for his "The River of Dreams"... that's what he was doing. I present you with:

Exhibit A: Billy Joel with his three backup singers, standing on an old swing truss rail bridge. Where ever could it be?

Exhibit B: Hey, that looks familiar! It's the Providence & Worcester rail bridge, along with the Arrigoni Bridge in the background! Why, they're standing on a bridge above the Connecticut River! A bridge that connects Middletown and Portland!

Exhibit C: These guys are chillin' on top of the "Come On Over" sign that beckons Middletonians to Portland. Except the lettering looks different. A mystery for another day...
