Poland was initially replaced by Jay Reynolds of Malice, but as the band began working on its next record, Reynolds was replaced by his guitar teacher, Jeff Young, when Megadeth was six weeks into the recording of its third album.
Han blev oprindeligt erstattet af Jay Reynolds fra Malice, men da bandet begyndte at arbejde på deres næste album, blev Reynolds afløst af sin egen guitarlærer Jeff Young, som kom med i Megadeth seks uger inde i indspilningen af deres tredje album.
