Hi, I am looking for the lyrics of a song that I dont know the name of but I think starts with,

Far away a spray of ivy clings around yon cabin door,
Far away the robin redbreast sings of sweeter days of yore,
Far away a light is burning in yon window clear and bright,
Far away but not forgotten someone thinks of you tonight.

Write a letter home to Mother, send your love to dear old Dad,
Tell them you are feeling happy, though you may be feeling sad,
