Abba star BENNY ANDERSSON refuses to dance to his band's greatest hits - he prefers to watch disco-goers enjoy their music instead. The Swedish star, 61, admits he has never danced to the Dancing Queen hitmakers' songs, but liked to see how much enjoyment his fans would have at the local disco. He says, "Every time we had a new song we used to take it and run down to one of the discos in Stockholm and play it at night to see if the mix was good or if we should go back and work on it. "So we heard our music a lot in discos but that's about it, I never dance, I'm sorry."
