Nurse, who led the Raptors to their first NBA championship in franchise history earlier this month, joined Hamilton rock band Arkells at their Toronto show to perform a song with them on guitar.
Fans posted photos and video on social media Saturday night of the rookie NBA head coach, clad in his signature black NN baseball cap, strumming along to a cover of Stevie Wonder’s hit “Signed, Sealed, Delivered I’m Yours” at Budweiser Stage.
The crowd can be heard cheering loudly in one video as Nurse makes his surprise appearance on stage.
Nurse had been photographed several times throughout the season — and Toronto’s playoff run — with a guitar flung over his shoulder.
The Raptors beat the Golden State Warriors in the NBA Finals in six games to win the Larry O’Brien Trophy on June 13.
