If you’ve ever been to an Action Pack Sing-along, you know that it’s a guaranteed good time. You get to sing along at the top of your lungs to your favorite songs without any shame, because there’s a hundred people around you doing the exact same thing. It’s a party, it’s a celebration, it’s an experience like no other.

Now the Action Pack is bringing this signature event to the Highball, and they’re adding a special twist: you won’t know which sing-along they’re presenting until it begins! Of course, we’ll be giving you a few hints along the way, so if you want to try to solve the mystery in advance, make sure you’re following the Highball (@highballaustin) and The Action Pack (@theactionpack) on Twitter or Facebook.

And even if you don’t figure it out, we highly suggest you show up anyway, because you won’t be disappointed. Trust.
