William Ryan Key (born December 17, 1979) is an American rock musician.
 He is best known as the former lead singer, songwriter, and rhythm guitarist of the former pop punk musical group Yellowcard.
Extended Versions is a live album by 10,000 Maniacs released in 2009 as a part of the Extended Versions collection of discounted albums.
 The album was recorded during the band's 2006 tour with Oskar Saville as lead vocalist.
 By the time of the album's release, Saville had been replaced as lead vocalist by the former member Mary Ramsey who is pictured on the cover and listed as a member of the band.
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.
"Trouble Me" is a song by the American alternative rock group 10,000 Maniacs and the first single from their 1989 album "Blind Man's Zoo".
 The single was co-written by the band's then-lead singer, Natalie Merchant, as dedication to her father, Anthony Merchant.
 "Trouble Me" charted in the both United States and the United Kingdom, becoming a hit for the band.
 A live version with lead vocalist Mary Ramsey was also included on their 2016 album "Playing Favorites".
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".
Playing Favorites is a live album by 10,000 Maniacs released in 2016.
 The album was recorded on September 13, 2014 at the Reg Lenna Center for the Arts in Jamestown, New York.
 This is their first live album with current lead vocalist Mary Ramsey and also marks the return of founding member John Lombardo who contributes lead vocals on "My Mother the War".
Our Time in Eden is the fifth studio album by American alternative rock band 10,000 Maniacs.
 It was released in 1992 on Elektra Records.
 The release is 10,000 Maniacs' last studio album with the original lead singer, Natalie Merchant.
 The album included her future replacement Mary Ramsey on violin and viola on such tracks as "Stockton Gala Days" and "How You've Grown".
 Singles released from the album were "These Are Days", "Candy Everybody Wants" and "Few and Far Between".
 The brass and woodwind section is covered by the J.B.'s, or James Brown's band.
Triangles is a 2011 EP by 10,000 Maniacs released on Ruby Wristwatch Records.
 It is the band's first release of new material since the death in 2000 of lead guitarist Robert Buck, as well as the first 10,000 Maniacs album with the singer Mary Ramsey without her songwriting partner John Lombardo, who left the band for the second time in 2003.
 Replacing Buck in the band is Jeff Erickson, who had been Buck's guitar technician since the Love Among The Ruins tour in 1997.
Mary Ramsey (born 24 December 1963), a resident of Buffalo, New York, is a member of folk rock duo John & Mary and lead singer and violinist for the American alternative rock band 10,000 Maniacs.
 Ramsey has also worked with other well-known artists such as Jackson Browne, Goo Goo Dolls, Billy Bragg, Warren Zevon, Alex Chilton and Ani DiFranco.
"Like the Weather" was the second single released from 10,000 Maniacs' 1987 album "In My Tribe", following "Peace Train".
 A live version with lead vocalist Mary Ramsey was also included on their 2016 album "Playing Favorites".
