Hamish Blake, Tim Minchin Bring The Goods For Playschool's 50th Bash

"Play School Celebrity Covers" is happening and the line-up is epic.

Hamish and Little Ted.

Jemima, Big Ted and Humpty know a thing or two about throwing a good party and Playschool's 50th happening this July is no exception.

To mark 50 years, Australia's longest-running children's series will present "Play School Celebrity Covers" where the nation's most loved celebrities will pop on their presenting hat to read a story or perform a song.

The guest list for the special occasion? To name a few, Hamish and Andy, Molly Meldrum, Magda Szubanksi, Tim Minchin and Carrie Bickmore.

But it doesn't stop there.

You can expect appearances from Annabel Crab with Leigh Sales, Adam Goodes, comedian Josh Thomas and yes, even Emma Wiggle.

You could say it's the party of the year.

From July 4, episodes will air daily on ABC KIDS at 8am and 5pm.

July 18 marks the program's official birthday where a half hour collection of a number of the mini episodes, "Play School Celebrity Covers Special", will air on ABC KIDS at 6.30pm.

The series will also be available on ABC iview.
