Black Monday occurred on October 19, 1987 just as Little Lies was burning up the US charts. There has always been speculation that the global shock of Lindsey's departure caused one of the biggest market crashes in history plunging the stock market over 20%.
Coincidence? I think not. Just a few weeks after Black Monday, Little Lies hit its peak chart position fueled by this moment in rock history.
