Keith Urban interrupted a dinner date with his wife Nicole Kidman last week (ends10Jun12) for an impromptu performance with Australian rocker Jimmy Barnes.
The couple was dining at Lizotte's restaurant, near Sydney, where Cold Chisel star Barnes was performing when Urban decided to join his pal onstage.
They sang the band's hit Flame Trees and the venue's owner, Brian Lizotte, reveals Urban's appearance at the show on Wednesday (06Jun12) caused a buzz.
He says, "When Jimmy introduced Keith there was a split-second of silence before the place erupted. I knew in advance but I couldn't tell anyone. We knew what would have happened; huge crowds and more security (required)."
