The Wiggles sing Frozen and Happy (exclusive video!)

Since my kids are almost seven and nine, it’s been a while since we’ve all sat down together to watch The Wiggles. So, hanging out with them yesterday afternoon was like a blast from the past—and more than that, it was fun! Anthony, Emma, Simon and Lachy (a little jetlagged from their long trip from Australia) were hilarious. As you’ll see in their Frozen medley down below, there were lots of giggles during our visit.

One dad of a five-month-old baby girl was actually bouncing off the floor, and his colleague, mom of a 13-month-old, had to keep biting her lip to contain her utter glee. I’m thinking a lot of you are just as excited to see this special performance, so, enough talk! Here are the Wiggles singing (and giggling) Pharrell Williams’s "Happy" and a Frozen medley—special for Today’s Parent readers! (For some reason, the videos have moved to the top of the page on some browsers..., so forgive the formatting here!)

And the Frozen medley...

Funny, right?! To top it all off, Lachy insisted we do a selfie, so...
