The Manchester United legend and movie icon performed on stage in Lyon with the gig's support act, The Clash's Mick Jones.
The Looking for Eric actor was attending an event organised to benefit the victims of the Hillsborough disaster.
Cantona performed a duet of anthem 'Should I Stay or Should I Go?' with Jones, who was collaborating with The Farm and Pete Wylie.
The elusive Frenchman, 46, was originally expected to accompany the Stone Roses on stage.
Sheila Coleman, a spokeswoman for the Hillsborough Justice Campaign, told the Liverpool Echo: "The HJC is thrilled that Eric Cantona spent some time with the band's musicians.
"Eric knows all about the campaign and he said that he supports it – and Ian Brown from the Stone Roses has given his backing too. It shows the campaign for the truth transcends football rivalries."
The Madchester group's song 'This Is The One' is traditionally played at Manchester United's stadium Old Trafford as the players go down the tunnel.
