Justin Sane
Irish-American musician

Justin Cathal Geever (born February 21, 1973), known professionally as Justin Sane, is an American singer and guitarist. He was the lead guitarist, singer and songwriter of Anti-Flag, a punk rock band formed in 1988 in Pittsburgh, Pennsylvania that was known for its left-wing political views.
In 2023, Anti-Flag abruptly disbanded following multiple rape allegations made against Sane. He is currently being sued for rape under New York's Adult Survivors Act. Sane holds dual United States and Irish citizenship.
Music career
In 1988, Sane formed Anti-Flag with friend Pat Thetic. In a 2014 interview, Sane claimed that their first performance as a band occurred at his high school, that the band truly solidified in 1993, and that the 1988 iteration had "very little similarit[ies]" with "what Anti-Flag later became."
In 1996, they released their first album, Die for the Government. Later that year, Andy Flag left the band as a result of personal disputes. Various band members came and went during 1997 and 1998, after which they finally settled on a permanent line-up consisting of Sane as lead guitarist/vocalist, Thetic as drummer, Chris Head as guitarist/backing vocalist, and Chris "#2" Barker as bassist/second vocalist. In 1998, the band released their second album, Their System Doesn't Work For You.

Why this record matters
The phrase “irish-American musician” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q377813. The first chronological checks are 1973, 1988, 2023 and 2014.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
