The Cock
From Anecdotes about Nineteen Century Authors

To `Will Waterproof's Lyrical Monologue', first published in 1842, Tennyson added the words `Made at the Cock', i.e. the Cock chophouse in Fleet Street. The opening lines are addressed to the head waiter:

O plump head-waiter at the Cock,
To which I most resort,
How goes the time? 'Tis five o'clock.
Go fetch a pint of port . . .

On Sunday 5 August 1849, William Allingham, who was to become a sort of Boswell to Tennyson, went to the Cock to see what biographical scraps he could pick up, and noted the results in his diary.
