Zac chose to perform an extremely stripped down version of a ballad from their 2004 album, Underneath, called "Lulabelle." In Zac's words, it's a "beautiful song about a little girl," and every time it's performed, fans typically remain close to silent as they listen to it. Instead, there were multiple crowd members who kept yelling out and screaming, including the girl who yelled, "I want to lick your taint!"
Zac stopped the solo, "Seriously? I'm singing this beautiful song about a little girl and this drunk bitch is screaming... You can go home! I'm going to start that verse over so the rest of us can enjoy it."
This isn't the first time Hanson have asked crowd members to leave, though usually Isaac Hanson is the brother who asks rude concert goers to remove themselves.
He stops the solo at 1:36.

I don't blame him for stopping one bit. Zac hates solos in the first place so I can't even imagine how awful it is to be harassed during one. Every one loved him for calling her out.
