Victory Gardens (1991) is the debut album from John & Mary, recorded in 1990 just six months after the two met in December 1989 and immediately following their signing with Rykodisc.
 John Lombardo, former member of 10,000 Maniacs and responsible for much of their early music, brought elements of the early Maniacs sound with him.
 Combined with the classically trained Mary Ramsey's blend of folk and classical influences, the album is considered by some to be heir to the 10,000 Maniacs album "The Wishing Chair" (1985), critically acclaimed for linking traditional influences with the contemporary new-wave sound.
Hot Leg were an English rock band led by The Darkness frontman Justin Hawkins.
 The band consisted of Hawkins, Pete Rinaldi (of Anchorhead), Samuel SJ Stokes (formerly of The Thieves) and Darby Todd (from Protect the Beat).
 Their debut album "Red Light Fever" was recorded in London in early 2008, and was released on 9 February 2009 by Barbecue Rock Records.

Mary Ramsey Wood aka Mary Ramsey Lemons Wood (May 20, 1787/circa 1810 (disputed) – January 1, 1908) was an American pioneer known as the "Mother Queen of Oregon".
 She was reported to be the oldest living person in the United States when she died, supposedly at the age of 120.
 It is said she traveled to the Oregon Territory across the Oregon Trail at the age of 66.
 There is evidence this age claim was inaccurate or exaggerated, however, and she may have been between 96 and 98 when she died.
Love Among the Ruins (1997) was the first album released by 10,000 Maniacs with their new lead singer, Mary Ramsey, after Natalie Merchant left in 1993.
 The two singles from the album, "More Than This" and "Rainy Day", were not originally intended to be included on the album at all.
 John Lombardo had just written "Rainy Day", which was deemed more radio friendly than the other songs, and the record company insisted that the band record a cover song for inclusion.
 The band chose to credit the songs as group collaborations so that all members would receive equal royalties.
 Ramsey and Lombardo shared the lyric writing.
 Ramsey wrote the music to "All That Never Happens".
 Lombardo wrote "Rainy Day", "Even with My Eyes Closed", "Big Star", "Shining Light" and "Across the Fields".
 Lombardo shared a writing credit with Jerry Augustyniak on "Girl on a Train".
 Rob Buck wrote "Love Among the Ruins", and Dennis Drew wrote "A Room For Everything".
 A live version was also included on their 2016 album "Playing Favorites".
