Classic Poem

Grave Dean of St Patrick's, how comes it to pass,
That you who know music no more than an ass,
That you who was found writing of Drapiers,
Should lend your cathedral to blowers and scrapers?
To act such an opera once in a year
Is offensive to every true Protestant ear,
With trumpets and fiddles and organs and singing,
Will sure the Pretender and popery bring in.
No Protestant prelate, his Lordship or Grace,
Dare there show his right or most reverend face;
How would it pollute their croziers and rochets,
To listen to minims and quavers and crotchets?
