My Bonny Boy is an English folk song (Roud #293) which is featured as the second movement of Ralph Vaughan Williams English Folk Song Suite.
'Twas up the wild forest and through the green groves Like one that was troubled in mind, I hallooed, I whooped and I blew on my flute But no bonny boy could I find.
I looked up high and I looked down low The weather being wonderful warm; And who should I spy but my own bonny boy Locked fast in another girl's arms.
He took me upon his assembled knees And looked me quite hard in the face, He gave unto me one sweet smile and a kiss But his heart's in another girl's breast.
Now the girl that enjoys my own bonny boy, She is not to be blamed, I am sure, For many's the long night he have robbed me of my rest But he never shall do it no more.
