Play or Musical with the longest run time

Hi all!

I was just wondering what play or musical had the longest run time in history. Either in multiple parts (like the 8 and 1/2 hour 2 part Nicholas Nicklebly) or just in one shot! I tried googling it but all I get it results for longest running shows! Thanks!

The Iceman Cometh is all in one shot and it's nearly 5 hours long. Taylor Mac also just did a 24-hour performance piece, but I'm not sure if one could consider that a play in the traditional sense.

Besides Iceman, my recent memory comes up with:

Long Day's Journey Into Night: ~ 4 hours

Ivo van Hove's Kings of War: ~4.5 hours

Angels in America: 3 hours + 3.5 hours = ~ 6.5 hours total

Intelligent Homosexual's Guide... = ~ 4 hours

Coast of Utopia: I believe the marathon performances (3 parts) ran 8 or 9 hours?

The Flick is a little over 3 hours, yes...

And bless anyone who can appreciate plays of this magnitude...as much as I wish I had the focus-span, they just aren't for me...

Elevator Repair Service's adaptation of The Great Gatsby was around 6 hours, I believe.
