for my voice lessons i was told to go and practice this song at home and have it learned by my next lesson (wich just happens to be tomorrow) but i have no clue how it goes and i cant look for it on you tube cos i dont know what its called…it goes
sleep my baby rest my loved one softly slumber now with me clasped in mothers arms so tender warm in mothers love for thee not shall ever come to harm thee while my loving watch i keep thou my pretty one shall slumber while i sing thy lullaby sleep my baby rest my loved one while the evening shadows creep why my birdie art thou smiling smiling sweetly in thy sleep? can it be that baby angels in gods heaven smile on thee rest my darliing smile and slumber while i sing thy lullaby
