When the comedian Ronnie Barker died, he had a memorial service at Westminster Abbey, and the choir entered behind the vergers carrying four candles (this joke may need explaining – check YouTube).
By the way, not everyone buried in Poets’ Corner is a poet. Thomas Parr lived through the reigns of ten monarchs, from Edward IV to Charles I, fathered a child out of wedlock at the age of 100 was supposed to have lived to 152, when he was finally killed by the shock of coming to London. I’d take that with a pinch of salt, though.
I’ve only ever been there once, to a wedding. If you’re an MP, your children can marry there.
