- Mumble Theatre

"Four dangerously good singers and a hilarious MC/ Pianist" (Three Weeks) deliver a performance rich in glorious vocals, cheeky humour and poperatic flamboyance. With previous performances spanning Classic FM and BBC Wales to the Pheasantry and the Edinburgh Fringe Festival, ‘All That Malarkey’ are performing across the UK to critical acclaim, fast becoming known on the London Cabaret circuit for their “striking, bold and often humorous” operatic re-imaginings of iconic hits from the history of popular music.  

Classically trained at the Royal Welsh College of Music and Drama and The Royal Academy of Music, ATM’s singers take an operatic approach to hits from Gershwin to Gaga, The Beatles to Britney, celebrating 80s and 90s pop nostalgia, classic power ballads and jazz standards - like you’ve never heard them before..! 


ATM work with you to masterfully tailor a programme to suit your party, venue, or event, and can also offer bespoke musical arrangements by our composer-in-residence, MC and compere David George Harrington, who has previously produced work for Katherine Jenkins, Justin Bieber, Kylie Monogue, and the BBC.


 Please feel free to get in touch here to find out how they can add that little bit extra to your event!

Amy is David's wife and hag. He hopes one day she'll think to brush her hair. It's a Pterodactyl's nest.
