Fegan starred as Inspector Jack Connolly, head of the squad – a seasoned policeman in the classic dry, gruff mould that remains popular in similar shows today.
The name Connolly was selected to reflect the Irish influence in Australian police forces and no doubt it helped to account for Fegan's still strong Belfast accent.
Fegan, as Inspector Connolly, is standing in the centre of the stamp, flanked by fellow original cast members Lex Mitchell and Terry McDermott.
Packer, who had been a boxer in his younger days but who at the time was in his mid-sixties, declared that they were doing it wrong and demonstrated the correct technique by putting the actor playing the police officer in a headlock.
According to an article about the event in the Sydney Morning Herald[citation needed], Packer's hearing aid came flying out and Fegan lashed out and crushed it with his foot.
Radicalised both by his formative years as a Belfast Catholic (having been involved with the Fianna before leaving Northern Ireland) and the Great Depression, Fegan was active in a variety of left wing movements associated with the Australian labour movement in Sydney throughout in particular his early life, including the Communist Party of Australia (CPA), the Sydney variants of the Unemployed Workers Movement/Workers Defence Committee (UWM/WDC) and a small group called the "Irish Terrorists Association" (one of the ten members of which it later turned out was an undercover policeman).
