Prior to joining Kingdom Come , Stag played in L.A. based bands Population 5 , and WWIII ; along with future Kingdom Come bandmate , Johnny B. Frank , a former keyboard player for Josie Cotton . Stag 's big break in the music industry came shortly after his good friend Johnny B. Frank was chosen to play in Lenny Wolf 's new band Kingdom Come . Wolf had asked Frank if he knew any blues guitarists and Frank recommended Stag . At the audition , Wolf asked Stag to improvise a solo for their upcoming single , " What Love Can Be , " which resulted in Stag landing the lead guitar duties for Kingdom Come . The band 's debut album '' Kingdom Come '' quickly climbed the billboard charts peaking at number 12 , with worldwide sales greatly exceeding one million copies . Kingdom Come were one of five bands selected ( Scorpions , Metallica , Van Halen , and Dokken , the others ) to appear on the Monsters of Rock Tour 1988 . Of the several tour dates included a stop in Stag 's hometown of Pittsburgh , where the band played in front of over 30,000 people at the Three Rivers Stadium . The band capped off a busy 1988 with a show headlined by Bon Jovi in Tokyo on December 31
