i'm singing this in choir, so here is the complete song:

A little boy and a little girl in an ecstasy of bliss
said the little boy to the little girl "pray give me just one kiss" the girl drew back in great surprise, 'you're a stranger sir!" said
and i will give you just one kiss
when the apples grow on a lilac tree
so bright and early on the very next morn he was quite surprised to see
his little sweetheart standing in the garden
tying apples on a lilac tree

hope i could help
