Thus it was that with the end of hostilities Joe Cassidy was twenty-four. And once back at Parkhead he was in the first team a year later, a left-winger to start with but converted to centre-forward. And as such he would win the League in 1922, the same year that in Paisley he married a local girl, Sarah Smith, and the Cup in 1923 by then aged twenty-nine and probably with his best days behind him. 

Yet at that point Bolton Wanderers fourth in the English First Division were still willing to buy his services. Nor did it appear to do them any harm. At the end of the 1924-25 season they were up a place and Joe had started twenty-two games, scoring seven. However, by the summer he was on his way and on a journey that would take in six clubs over the next seven years. For a season he was in Wales at Cardiff still in the First Division for twenty-four appearances, then back to Scotland at Dundee and Clyde for three campaigns, Ballymena in Ireland for two more and the Irish cup and finally short contracts on both side of the Irish Sea to final retirement at thirty-eight in 1932. 

And sadly from then on did not treat him kindly. He would suffer tragedy, imprisonment and finally terminal cancer, from which he would die in 1949, in Paisley, at the age of fifty-five. He would be interred at Craigton Cemetery, survived by Sarah for forty years, she passing away in Paisley once more in 1988.
