Also a traditional folk hymn, which we used to sing at my church when I was a kid. As with many traditional folk songs, the lyrics and melody are a bit repetitive, but kind of soothing. And you can dress it up with harmonies.

We are climbing Jacob's ladder
We are climbing Jacob's ladder
We are climbing Jacob's ladder
Brothers, sisters, all

Every rung goes higher and higher
Every rung goes higher and higher
Every rung goes higher and higher
Brothers, sisters, all

We are dancing Sarah's circle
We are dancing Sarah's circle
We are dancing Sarah's circle
Sisters, brothers, all

Every round a generation
Every round a generation
Every round a generation
Sisters, brothers, all

We are climbing Jacob's ladder
We are climbing Jacob's ladder
We are climbing Jacob's ladder
Brothers, sisters, all
