The new tune is also available for streaming now.
Homegrown hero Courtney Barnett has revealed she had a major hand in the upcoming reboot of the classic '90s kids film Harriet The Spy.
Taking to Instagram to share the news, the Aus musician unveiled that she wrote and performed the theme tune for the new cartoon series - based on the novel by Louise Fitzhugh, originally released in 1964. Barnett also shared that the song has been released as a standalone single, and is available for streaming now.
Smile Real Nice was recorded in Melbourne with Warpaint drummer Stella Mozgawa on percussion and bass, and producer extraordinaire Guus Hoevenaars engineering and mixing the track. Hoevenaars has been a key figure in the Aus music scene as of late, recording such massive tunes as Tone And I's Fly Away, Vance Joy's Missing Piece, and many more.
