I think this is the right version!!

See the little birch in the meadow
See the leaves a-dancing when the wind blows
Loo-lee-loo when the wind blows
Loo-lee-loo when the wind blows

From the little tree take three branches
Make three silver flutes from silver branches
Loo-lee-loo silver branches
Loo-lee-loo silver branches

From the tree I'll carve my balalaika
With the flutes I'll play my balalaika
Loo-lee-loo balalaika
Loo-lee-loo balalaika

As I play my tingling balalaika
I'll remember you my little birch tree
Loo-lee-loo little birch tree
Loo-lee-loo little birch tree

I hope it will help!!
