Unmasked Tusken raider on Luke's Skiif in ROTJ?

Just watched ROTJ (for probably the 12,694,863rd time) and during the skiff battle when Lando is sturggling back and forth with what looks like a Nikto there's an alien noise that sounds damn clsoe to that of a Tusken Raider's battle cries. I've noticed this before and podered quite a lot over it and finally decided to take it up with others that may feel the same or possibly indifferent about it. I played through it a few times to check it over and I'm nearly positive of what I'm hearing, I've been hearing for years.
Although it wouldn't be the first time I've had delusions of granduer, I just want to see if there's anyone with me on it....
....don't y'all love shared hallucinations

 

You've only seen it 12,694,863 times?

...Rookie...


I think its a Tusken, probably off screen...

 

I think I know what you're talking about, but I think it's just a grunt Lando is making as he struggles with the Nitko for possession of the gun.

 

Yeah, that noise is Lando's grunt.

 

No, it's the noise Chewies stomach makes when he's thinking.
