Seriously? This is about the Jones Beach dustup 10 years ago? How can you tell?
The article mentions it pertains to a show where they tried to get Al to appear with Mike and David Marks. The only time we know of since the reunion tour (other than that Ella Awards gig) where they tried to get Al to appear with Mike and David was at that Jones Beach 2014 gig.
I'm curious what the statute of limitations is on such actions. It had been over nine years as of when that video was supposedly shot.
From what I've heard about the Jones Beach debacle, I don't know that the guy bringing this suit would have much success.
Separately, as I'm sure someone explained to Al if he didn't already know, you can't evade a process server by just not agreeing to take the papers.
