Karaoke crowd freaks when actual rock singer shows up

Mickey Dolenz, who sang many of the Monkees' hits, was having dinner at Elaine's in New York when someone realized that people in a karaoke club a few doors away were all singing along to one of his hits, "I'm a Believer." Dolenz was summoned, entered the karaoke bar, and the result was pandemonium.

The best part of the story was that it was a coincidence that Dolenz was nearby when the song -- which was repopularized in the 2001 film Shrek (YouTube clip here) -- was chosen by the under-20s at the karaoke club; they didn't know he was near.
