Gillis, who later became a key member of Night Ranger, joined Ozzy’s band in 1982 following the tragic death of guitarist Randy Rhoads. He stepped into an enormous role during the Diary of a Madman tour and subsequently played on Ozzy’s live album Speak of the Devil.
Given that history, some fans wondered why Gillis was not among the musicians who appeared at Ozzy’s farewell event, Back to the Beginning, in Birmingham on July 5, 2025.
In a new interview, Gillis explained that his absence was not caused by any falling-out with Ozzy or his family. Instead, he was already committed to touring with Night Ranger and could not simply abandon those arrangements.
Gillis said the decision came down to his responsibility to the band and its crew. With Night Ranger already working and people depending on the tour, cancelling his commitments would have affected far more than just himself.
His explanation adds an important piece of context to the emotional farewell concert. Back to the Beginning brought together several major figures from Ozzy’s career, while also serving as a celebration of his extraordinary contribution to rock music.
Gillis’ connection with Ozzy goes back more than four decades. He was brought into the band under extraordinary circumstances after Rhoads’ death and had to learn the demanding material in a very short period of time. He later returned to Night Ranger as the group secured its record deal.
Although he was unable to attend the final show, Gillis has made clear that he remained grateful for the opportunity Ozzy gave him.
Following Ozzy’s death in July 2025, Gillis paid tribute to his former bandmate during a Night Ranger performance, describing the loss as deeply painful and remembering Ozzy as the person who gave him his start.
For fans who wondered whether Gillis’ absence from the farewell concert carried any hidden meaning, his latest explanation appears to settle the question.
It was not about resentment or a broken relationship. Gillis simply had existing professional commitments that he felt responsible for honouring.
And while he was not on stage for Ozzy’s final performance, his place in the singer’s history remains significant. He stepped into one of rock’s most difficult guitar roles at a crucial moment in Ozzy’s career and helped carry that music forward during a turbulent period.
His story is therefore another reminder of the many musicians who contributed to Ozzy Osbourne’s remarkable career—and of the complicated schedules and commitments behind one of rock’s most emotional final goodbyes.
