Prior to the band's fourth release, the aptly titled 4, Foreigner again sustained lineup changes. With the departures of Ian McDonald and Al Greenwood, Foreigner became a quartet for the first time. The streamlining of the lineup helped bring about even greater commercial success for the band, as 4 became Foreigner's best-selling album ever, eventually selling well over six million copies in the U.S. alone. Its success can also be attributed to the presence of superproducer Robert John "Mutt" Lange. The presence of the gigantic hit ballad "Waiting for a Girl Like You" and the well-known rockers "Urgent" and "Juke Box Hero" certainly didn't hurt either. Looking back, 4 has proven to be Foreigner's apex.|
