Is this the one you mean?
Here's a health to the bird in the bush
Here's a health to the bird in the bush.
For all birds of one feather
They should all flock together,
Let the people say little or much.
And here's a health to the jolly dragoon,
Here's a health to the jolly dragoon.
For we've tarried here all day,
To drink down the day,
Let us tarry now to drink down the moon.
From the Music of Sharpe, John Tams, Dominic Muldowney.
