in europe, "stop loving you" was the album's first single where it reached the top ten in several countries. following the album's release, toto embarked on a tour of sold-out arena shows in europe. while joseph williams' vocals were not a point of contention during the "fahrenheit tour," he struggled with his vocals during the european tour, likely as a result of substance use. in particular, williams was unable to perform during toto's first show in amsterdam, a show which was simultaneously broadcast live on national radio. though efforts were made to control williams' drug use, ultimately jeff porcaro fired him from the band. williams was the third vocalist fired from toto due to inability to perform vocals, following the previous termination of bobby kimball and fergie frederiksen. he would later contribute vocals to the "falling in between" album and return as the lead vocalist for "toto xiv."
