My transcription from Spotify:
LET US COME IN
As sung by Pete Seeger on "Song and Play Time" (1960)
1. We are three wand'ring trav'lers
Out in the wind and the rain.
We saw your light, cheery and bright,
And tapped on your window pane.
Singing let us come in, let us come in,
Into your house so gay.
Let us come in, let us come in.
Please do not send us away.
2. One of us plays on the whistle.
He makes such a musical tweet.
One of us sings such beautiful things,
And another keeps time with his feet.
3. Please go ahead with your dinner.
We will just wait till you're through.
But if you find there's enough to go round,
Save us a beefsteak or two.
4. We will make noise very softly.
The landlord won't hear us at all;
And if there's not enough room in the beds,
We'll just sleep out in the hall.
5. One or two extra won't matter.
Plenty of room on the floor.
You'll look around and find we have gone
After a fortnight or more.
