Flow, sweet river, flow

The view from the 72nd floor

From Shadwell dock to Nine Elms Reach
We cheek to cheek were dancing
Her necklace made of London Bridge
Her beauty was enhancing
Kissed her once again at Wapping,
Flow, sweet river,  flow
After that there was no stopping,
Sweet Thames, flow softly…

Or, if you must (and you should), the original by its originator:

Though, even that has a progenitor:

From those high towers this noble lord issúing
Like radiant Hesper, when his golden hair
In th’ ocean billows he hath bathèd fair,
Descended to the river’s open viewing…
     Sweet Thames! run softly, till I end my song.
