 The decision to leave The Schoolboys was an important one, because it marked the turning point that led to Henzerling's relocation to Los Angeles in 1984 to join the band Keel.Henzerling played only one show with Keel, in March 1984 at Perkins Palace in Pasadena, California, where he was quickly spotted and recruited by veteran drummer Carmine Appice (Vanilla Fudge, Rod Stewart, Ozzy Osbourne) for a new band being formed called King Kobra.Shortly after joining, the band's manager suggested David change his last name from "Henzerling" to something more Hollywood-friendly, so the pseudonym "Michael-Philips" was adopted (the use of Philips came from David's middle name).
