Nice title name my friend!

Lamp dates to July 1995??? Okay that's probably why it's dead!

It look like there was severe overcurrent, so i would rather guess the ballast failure...

Judging by the arcing at the lead wire that you described, it sounds like a partially shorted ballast, rather then a bad lamp!

From what you describe, it may not be a bad ballast. It is possible that when the wire broke, the resulting arc ionized the outer fill gas and caused the meltdown. Unlike the tungsten electrodes in the arctube, which can glow white hot in MH at thousands of degrees, the outer metal supports would melt quickly with sustained arc under normal ballast current.

I wonder if leaving it arcing would kill the ballast or just be a cool show?

This was in one of the Reveres with a MH ballast. It wasn't lighting, so I bumped the bulb and it started to light, then the lead wire sprung away drawing a bright pink arc. I immediately shut it off, this is what's left.
