The singer showcased his new single 'Can't Say No' ahead of its official release on Sunday (April 15) at a secret gig at a restaurant in London.
Maynard was preceded by rising stars Clement Marfo and The Frontline, Cleo Sol and Tanya Lacey.
Lacey performed two of her own hits along with Loick Essien's 'How I Roll', on which she features, and will.i.am's 'T.H.E.', which she co-wrote.
Speaking about the gig, a Nando's spokesperson commented: "It was an incredible way to show off our latest restaurant.
"Everyone had an amazing night, thanks to Conor and all the other performers, and of course our Nando's team who kept us all topped up with peri-peri treats."
The restaurant was packed with guests including Stooshe, Louisa Lytton and Preeya Kalidas.
Maynard recently told Digital Spy that the idea of releasing his debut single is scary.
