What happened to Brian Connolly?

His final years after leaving Sweet

  • Connolly left Sweet in 1979 after a legal dispute over the band name (Wikipedia).
  • He formed a new band called Brian Connolly and the New Sweet but legal issues prevented him from using the Sweet name (Wikipedia).
  • In 1981 he was hospitalized with bloating and multiple heart attacks; his health never fully recovered (Wikipedia).

After the 1981 episode, Connolly suffered paralysis on his left side and a later neurological disorder (Wikipedia). He continued to tour sporadically but his voice and physical stamina had noticeably changed.

Cause of death and health issues

  • Connolly died at Wexham Park Hospital on 9 February 1997 (Wikipedia).
  • The official cause was kidney and liver failure, compounded by repeated heart attacks (Wikipedia).
  • According to a contemporaneous Google Groups discussion, Connolly himself admitted “booze was my downfall rather than drugs.”
The trade-off

Connolly’s chronic alcohol consumption, combined with prescription diuretic medicine, accelerated his organ failure. His heart stopped six times during recovery from his second heart attack, yet he had renounced alcohol after the first two — too late to undo decades of damage.

The implication: By the time Connolly quit drinking, his body had already sustained irreversible harm. His death at 51 was a predictable outcome of a pattern that began in the mid-1970s.

Why did Brian Connolly leave Sweet?

The legal battle over the band name

  • In 1979, Connolly left Sweet after a dispute regarding the rights to the band name (Wikipedia).
  • He attempted to continue as Brian Connolly and the New Sweet, but a legal injunction prevented him from using the name (Rock-Zone (music history blog)).
  • According to Rock-Zone, the legal battle was partially fueled by Connolly’s deteriorating health and unreliable behavior.

Why this matters: The dispute effectively ended Connolly’s ability to trade on the Sweet legacy, forcing him into solo work that never matched the band’s commercial peak.

Solo career and later projects

  • After leaving Sweet, Connolly released solo material and toured with a new lineup, but none of his post-Sweet recordings charted significantly (Wikipedia).
  • He also made two guest appearances on the TV series Taggart in the 1980s, playing a minor role (Wikipedia).

The catch: Connolly’s acting sideline hints at a man trying to reinvent himself, but his failing health and legal entanglements kept him from building a sustainable second act.

Are any members of Sweet still alive?

Which original Sweet members are deceased

The status of surviving members

  • Guitarist Andy Scott is alive as of 2025 and continues to perform with his own version of Sweet (Wikipedia).
  • Early member Frank Torpey (original guitarist) is also deceased, having died in 2017 (Wikipedia).

The pattern: Of the classic lineup (Connolly, Tucker, Priest, Scott), only Andy Scott remains. The band’s legacy now rests largely on his performances and the enduring popularity of their 1970s hits.

Was Brian Connolly related to Mark McManus?

Mark McManus and the Taggart connection

  • Mark McManus was a Scottish actor best known for playing Detective Jim Taggart in the long-running series Taggart (Mark McManus Wikipedia).
  • McManus died in 1994, three years before Connolly (Wikipedia).

The rumor about a family relationship

  • Despite persistent online rumors, there is no evidence of a family relationship between Connolly and McManus (Wikipedia).
  • The confusion may stem from Connolly’s guest appearance on Taggart and the fact that both men were Scottish and died relatively young.

The implication: This is a classic case of internet folklore — two Scottish celebrities with overlapping careers and tragic early deaths, but no blood ties at all.

What is Brian Connolly’s legacy and recent tributes?

Connolly’s influence on glam rock

  • Connolly’s distinctive vocal delivery defined Sweet’s biggest hits, including “Ballroom Blitz”, “Fox on the Run”, and “Action” (Wikipedia).
  • Sweet sold over 20 million records worldwide and are considered pioneers of glam metal (Wikipedia).
Why this matters

Andy Scott summed it up in a tribute: “Everybody’s image of Sweet was Brian. It was what he was put on this earth for”.

His son Brian Connolly Jr.’s tribute project

The trade-off: While Connolly Sr. couldn’t sustain a solo career, his son is keeping the music alive for a new generation — a bittersweet continuation of a story that ended too soon.

Brian Connolly’s story is a stark reminder that fame offers no immunity from addiction.
