Rocker Jon Bon Jovi was left crushed when he failed to measure up to his avatar on karaoke videogame Rock Band.
 
The singer was persuaded to belt out one of his classics by his kids at home - and he couldn't believe it when his performance was considered a failure.
 
He says, "I took the microphone and sang sitting down and I failed. (I was like), 'Oh really?' I stood up and I looked in the TV and said, 'Let's go again!' I failed again.
 
"I said, 'Everyone goes to bed. Turn this silliness off.'"
