On Visiting Westminster Abbey

Holy Moses! Have a look!
Flesh decayed in every nook!
Some rare bits of brain lie here,
Mortal loads of beef and beer,
Some of whom are turned to dust,
Every one bids lost to lust;
Royal flesh so tinged with 'blue'
Undergoes the same as you.
...
Famous some were--yet they died;
Poets--Statesmen--Rogues beside,
Kings--Queens, all of them do rot,
What about them? Now--they're not!
