Rocker Billy Idol knew he had a hit on his hands with break-out tune Dancing With Myself when the song cleared a bar he was drinking in.

The White Wedding singer admits he had no idea if the song would be a smash but he felt good recording it and was thrilled when he realised it had become an overnight dancefloor favourite.

He explains, "I went to (a club) to kill the blues, have a few drinks and suddenly, this music came on, and the bar suddenly deserted, and these people are going... over tables and chairs and couches and armchairs to get on the dancefloor and start dancing. I was left alone with my drink, standing at the bar going... 'What the f**k just happened?'"
