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.

MSO's Ben Northey and Athina from Gut Health are guests this week with Cam James and Peter Helliar. Plus, the Bamboos guest star playing Look What They've Done to My Song Ma and the Closer - a killer version of the 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.

Adam, Myf and Alan are joined by Astrid Jorgensen, Zoe Coombs Marr, Ben Lee and part-time DJ but full-time Prime Minister, Anthony Albanese.

Will Hamish Blake replace Jason Arrow in Hamilton? Will Adam and Angie McMahon recite every Meatloaf lyric? Will Mel Tracina convince Alan she knows the secret song? Will Myf have to sing the whole song to work out the title?

Emily Wurramara, Claire Hooper, Ella Hooper and Brett Blake join Alan, Myf and Adam as they hit such musical heights they have to go into falsetto. There will be R&B, Irish music and some unfortunate innuendos.

Adam, Myf and Alan are joined by Jude Perl, Joel Creasey, Johnny Took and Abbie Chatfield. Plus, western swing with the Canyon Callers and so many Secret Song clues with Brian Mannix.

This week there's a lot to dig - Behani teaches Adam, Myf and Alan the Persian Snap, Tom Cardy dances to PSY, Brian Mannix regales with Countdown stories and Michala Banas tries to reach an invisible top shelf.

Adam, Myf and Alan join Gillian Cosgriff, Jenny Tian, Phil Jamieson and Tom Ballard as they find out why Stephen King's wife threatened to leave him and what Andrew Lloyd Webber really thought of Cats The Movie. (Final)
