Very rough- but perhaps some help. We need Escamillo.

1. A small fountain flows, clear and sonorous,
Nightingale, singing sadly in the woods
keep quiet while the cradle is rocked
to this little lullaby.

A little bouquet of roses and wallflowers(?),
what is in his dream that makes him smile?
What are your dreams which comfort my soul,
what is that he murmurs? The Eucharist.

Little birds and fountains, breaths and breezes,
respect this dream and these smiles,
keep quiet while the cradle is rocked
so that the child sleeps, blessed is he.

Coro
To this little lullaby,
my Jesus is asleep, blessed is he, blessed is he.
