The first episode back is a firecracker - Anthony Callea, Steph Tisdell, Tommy Little and Yve Blake. There will be questions about Aussie Belters, Musicals Fan Art, a traditional Guzheng ensemble plus the secret song.

Dan Sultan, Lou Wall, Nina Korbe and Dave O'Neil join Adam, Myf and Alan in a who-knows-what of music trivia. There will be bangers, smashes, blinders and delights, with a healthy dose of Cover Versions and weird collabs.

Adam, Myf and Alan are joined by Montaigne, Nooky, Zoe Coombs-Marr and Greg Larson. They will listen to some music, watch some videos and play some bells, but can they guess the secret song before Lime Cordiale plays it?

Adam Hills turns into the Riddler as he taunts Alan, Myf, Bec Charlwood, Dilruk Jayasinha, Groundhog Day's Elise McCann and Lime Cordiale's Oli Leimbach with tough clues that will anger your family. Special guest appearance by violinist Xani.

Marlon Williams, Geraldine Hickey, Big Wett and Rhys Nicholson join Adam, Myf and Alan as they hit such musical heights they have to go into falsetto by the end of it.

Adam, Myf and Alan are joined by Ross Noble, Ngaiire, Eamon Sandwith from the Chats, Meshel Laurie and Ghost Medium. They will sell their jewellery to solve this week's secret song.

You want great guests? No problem. Adam, Myf and Alan are joined by Fanny Lumsden, Shane Jacobson, Elly-May Barnes and Courtney Act. You want a spine chilling closer? No problem again. Folk Bitch Trio will stun you.
