It was Idol week at school and Adrian told his teachers and class that his dad was a "rockstar".
After Adrian's comment, John received a request from the teachers to come play some guitar for the preschool classes. So he brushed up on his ABC's, Twinkle, Twinkle and 5 Little Monkeys. Being in a couple bands back in the day is really paying off for dad.
He just might have a future in the Wiggles :)
