Mary MacGregor (album): Mary MacGregor is Mary MacGregor's fourth and final album, released in 1980.  After recording two albums for Ariola Records - who had also released a Mary MacGregor compilation - MacGregor had recorded the track "Good Friend" for the 1979 film "Meatballs" whose soundtrack album was released by RSO Records.  "Good Friend" had been sufficiently successful - reaching #39 on the "Billboard" Hot 100 - for RSO to sign MacGregor in December 1979.

The "Mary MacGregor" album is out of print and has never been issued on CD.
