When Clare produced their finest team in two decades to beat Cork and Tipperary in 1955, it was a young and unconsidered Limerick outfit, Mackey’s Greyhounds, who tripped them up in the Munster final on an afternoon of sub-Saharan heat on the Ennis Road. When Clare produced their next successful team two decades later, the bunch that won two National Leagues in the late 1970s, the big championship rivalry was with Cork but – all politics being local — the rivalry with Limerick wasn’t far behind.
