Mustaine Rules Out Former-Member Guest Spots on Megadeth Farewell Tour

Citing past conduct and a commitment to fairness for the current lineup, he says reunions are off the table.

Overview

He told Eddie Trunk he cannot stage a Black Sabbath–style reunion because of the past behavior of one former bandmate.
He did not name the musician, though reporting links the comment to ex‑bassist David Ellefson, who was fired in 2022 and has denied wrongdoing.
He praised a 2024 onstage reunion with Marty Friedman in Japan and said he could perform with members from those eras such as Chris Poland and Jeff Young.
The farewell run begins early in 2026, including Canadian dates with Anthrax and Exodus.
A final self‑titled album is slated for January 2026 and includes a cover of Metallica’s Ride the Lightning, while Ellefson recently said he hopes the farewell is not just a ticket‑sales boost.
