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.
 This resultant self-titled album produced a minor hit in "Dancin' Like Lovers" - #72 in the spring of 1980 - followed by the non-charting "Somebody Please" which was evidently MacGregor's final single release.
 The "Mary MacGregor" album is out of print and has never been issued on CD.
