Reinhard gives good coverage of this song at Mainly Norfolk, and sometimes I wonder if there's any need for me do duplicate what Reinhard has already done so well. We have lots of interesting information on the song in the thread titled Man in the Moon - old song? (particularly the posts from Mick Pearce), but that thread is confusing because there are other "Man in the Moon" songs mixed in. I thought I could use this thread to give a summary of the information we have on this particular song.
Here's a live performance of the song by The Full English:

THE MAN IN THE MOON (recorded by The Full English)

When a bumper is filled, it is vexing, no doubt,
To find when you rise that the wine has run out;
And sure it's an equally unpleasant thing,
To be asked for a song when you've naught left to sing.
I could sing something old, if an old one would do,
But the world it is craving to have something new,
But what to select for the words or the tune,
I, in fact, know no more than the Man in the Moon.

The Man in the Moon a new light on us throws;
He's a man we all talk of but nobody knows;
And though a high subject, I'm getting in tune—
I'll just sing a song for the Man in the Moon.

'Tis said that some people are moonstruck, we find,
That the Man in the Moon must be out of his mind,
But it can't be for love, for he's quite on his own—
No ladies to meet him by moonlight alone;
It can't be ambition, for rivals he's none—
At least he is only eclipsed by the sun,
But when drinking, I say, he is seldom surpassed,
For he always looks best when he's seen through a glass.

The Man in the Moon a new light on us throws;
He's a man we all talk of but nobody knows;
And though a high subject, I'm getting in tune—
I'll just sing a song for the Man in the Moon.

The Man in the Moon he must lead a queer life,
With no one around him, not even a wife,
No friends to console him, no children to kiss,
No chance of him joining a party like this.
But he's used to high life, all circles agree,
That none move in such a high circle as he,
And though nobles go up in their royal balloon,
They're not introduced to the Man in the Moon.

The Man in the Moon a new light on us throws;
He's a man we all talk of but nobody knows;
And though a high subject, I'm getting in tune—
I'll just sing a song for the Man in the Moon.

The Man in the Moon a new light on us throws;
He's a man we all talk of but nobody knows;
And though a high subject, I'm getting in tune—
I'll just sing a song for the Man in the Moon.
