WHAT exactly is a purple Wiggle? Silly question if you’re under the age of five, for surely everybody knows that the famous Wiggles come in colours.

Newish Purple Wiggle, “Lachy”, has wiggled his way to taking over from founding member Jeff Fatt at the beginning of this year.

Small matter that his real-life alter-ego, Lachlan Gillespie, was also recently named in “Cleo” magazine’s top 50 bachelors. When it comes to theatrical clout, being a Wiggle is just about as good as it gets.

He started playing the piano at age four and started singing training at age 12. Then he graduated with a BA in musical theatre from the WA Academy of Performing Arts.

“Back in 2009, just after graduating, a friend told me to audition for the Dorothy the Dinosaur show, which was about to tour NZ,” he tells me.

He got in, found himself playing Captain Feathersword for two and a half years, then a Wiggly Dancer, and then Wags the Dog during the group’s regular tour.”

Not everyone knows that the Wiggles take time off each year to compose their own original material, that’s partly the key to their success.

“I’m really thriving from the Wiggles experience, continually composing new material in a random way as I sit at the piano… I don’t think there have been any lemons, yet.” Lachy says.

“I’m so happy I ended up here. I’ve always loved children and I’ve always written songs.”
