Foreigner guitarist Mick Jones and vocalist Lou Gramm wrote this song after seeing New York Rangers goalie John Davidson get knocked out during the 1977 Stanley Cup Playoffs. Jones told us: "That's where the title came from. We were at a hockey game. I was an avid Rangers fan in those days, and Lou and I went to a game, and the goaltender for the Rangers got a concussion, and it was announced over the PA that he was taken off and was suffering from double vision. I'd never heard that term before, and we picked up on it. And then that led to the title for that song. I know it was received by a majority of the public as a drug song. I didn't mind that, you know. It wasn't the intention in the beginning, but that's how a lot of people interpreted it."
