We have two young grandchildren and we love the Wiggles. We’re lucky enough to have met them and they are terrific blokes. We’re also old enough to remember seeing them play as The Cockroaches in their rock past.

It’s great to see Greg, the yellow Wiggle, recovered from his medical problems and back in the team but his return provides a lesson to us all.

Greg left previously and was paid a substantial amount for his shares in the extraordinarily successful Wiggles business.

He ploughed that payout into property developments which went sour and he lost most of his money.

He put all his investment eggs in the one basket, received poor advice and didn’t do his homework well enough.

It’s a tough lesson for anyone to learn.
