Talk about a wedding ringer. Jon Bon Jovi put his famous pipes to use with a surprise performance of his 1986 hit “Livin’ on a Prayer” at a wedding reception in Miami last weekend.

Captured in a video posted to YouTube, the performance came as a surprise not only to the crowd, but also to Bon Jovi himself, who was attending as a guest. Nevertheless, he was enlisted mid-song by jazz singer Lourdes Valentin and reluctantly obliged.

Valentin told the Associated Press she knew Bon Jovi would be there and prepared the song specifically for him. He demurred before the party, so she was “very surprised” when he ultimately gave in.
