Mary has released a total of five solo CDs in which she sings and plays the keyboard. "A Celtic Journey" was her first CD and primarily consists of Irish songs but several tracks are of Scottish or Welsh origins. Her rendition of "Suo Gan" has been especially popular. Selections include compositions by the Irish Baroque composer Turlough O'Carolan and the Scottish poet Robert Burns along with many traditional songs including "Danny Boy" and "An Irish Lullaby."
"Kids' Songs and Lullabies" includes songs for both very young and somewhat older children. As might be inferred from the title, there are 12 lullabies on the CD including an original composition. Many of the other tunes fall into the "silly song" category that kids find enjoyable.
The "American Pie" CD features the Don McLean song of the same title along with a wide variety of earlier American songs that in one way or another describes interesting aspects of the American experience. A number of these older tracks on this CD have had successful reincarnations in modern times.
The "Amazing Grace" CD is a collection of traditional Christian music along with traditional American favorites include Amazing Grace, How Can I Keep From Singing? and The Battle Hymn of the Republic. Many of the songs are sung partially or entirely a cappella and feature rich polyphonic arrangements.
Her most recent CD, "Christmas Songs from Many Lands," is obviously Christmas music. While most of the songs are sacred in nature, her rendition of "Jingle Bells" has been popular with many listeners.
