The Dublin Waits, first on record from 1465 (though a band of pipers was already in existence by 1456), existed primarily to serve the civic weal, and were allowed to stray further afield in search of patronage only with the Mayor's prior approval and then only for brief periods. Their first duty was to be available in the city to service the machinery of civic ceremonial. Sometimes they functioned in close proximity to actual civic drama, as in 1561 when after dinner and a pageant of the Nine Worthies organised by the Mayor for the new Lord Deputy, Sir Thomas Radcliffe, the City Waits accompanied the Lord Deputy back to his lodging at the end of the evening.
Waits' livery of blue or watchet colour, bearing the city coat of arms.
In 1603, on the accession of James I, twelve yards of cloth allocated for the waits' new liveries. As typical amount for livery was three yards, that indicates four waits.
