This lovely old hymn to Our Lady always takes me back to my childhood: one of my earlest memories is of my mother singing it me as a lullaby (a great way to share the Faith with children from their earliest years). Evidently it was one of her favourite hymns as as a child. I wonder if anyone else had parents like this.
Sadly, this video does not include all the verses, but is still rather nice.
Mater Amabilis, ora pro nobis.
