Question: Which singer lived longer, Billy Mackenzie or Donnie Munro?
Context: Mara is the ninth album by Scottish Celtic rock group Runrig, released in 1995.  The title means 'of the sea' in Scots Gaelic.  It is the last album featuring Donnie Munro on vocals and the fifth and final album released on Chrysalis records. Calum MacDonald (Scottish Gaelic: Calum MacDhomhnaill; born 12 November 1953) is the percussionist of the Scottish Celtic rock band Runrig, as well as their primary songwriter with his older brother, Rory MacDonald.  Rory tends to write the melody, and Calum the lyrics.  Since former lead singer Donnie Munro left the band in 1997, Rory has taken lead vocal duties on songs in the band's catalogue written in the Scots Gaelic language, as the band's new lead singer, Bruce Guthro, is not a Gaelic speaker. William MacArthur "Billy" MacKenzie (27 March 1957 – 22 January 1997) was a Scottish singer, with a distinctive high tenor voice; he was best known as a member of The Associates. Roderick (Rory) Macdonald (Scottish Gaelic: Ruaridh MacDhomhnaill; born 27 July 1949, Dornoch, Sutherland) is the bassist of the Scottish Celtic rock band Runrig, as well as their primary songwriter with his younger brother, Calum Macdonald.  Rory tends to write the melody, and Calum the lyrics.  Since former lead singer Donnie Munro left the band in 1997, Rory has taken lead vocal duties on songs in the band's catalogue written in the Scottish Gaelic language, as the band's new lead singer, Bruce Guthro, is not a Gaelic speaker. The Associates were a Scottish rock act, formed in Dundee in 1979 by singer Billy Mackenzie and guitarist Alan Rankine.  The group first gained recognition after releasing an unauthorized cover of David Bowie's "Boys Keep Swinging" in 1979, which landed them a contract with Fiction Records.  They followed with their debut album "The Affectionate Punch" in 1980 and the singles collection "Fourth Drawer Down" in 1981, both to critical praise. Donnie Munro (Donaidh Rothach) (born 2 August 1953) is a Scottish musician, and former lead singer of the band Runrig. On The West Side is the debut solo album by the Scottish folk rock artist Donnie Munro, former lead singer of the band, Runrig.  It was released in 1999. Chain was Edinburgh musician Paul Haig's third album and was released in May 1989 on Circa Records, a subsidiary of Virgin Records.  "Chain", which Haig financed himself, was recorded and completed in 1988, but it sat on the shelf after the normally accommodating Les Disques Du Crepuscule decided not to take up the option of releasing it.  The album was co-produced by long-time Haig cohort, Alan Rankine, instrumentalist with celebrated Dundee band, The Associates.  There was another Associates connection on the album - the track "Chained" was written by Haig's good friend, Billy Mackenzie.  Haig returned the favour and gave Mackenzie the track "Reach The Top" for his album "The Glamour Chase", which after many years in limbo was finally released in 2002. "Say" is a song recorded by English band The Creatures (aka singer Siouxsie Sioux and drummer Budgie).  It was co-produced by Steve Levine.  The song is about the suicide of Billy Mackenzie of Associates. Clan Mackenzie (Scottish Gaelic: "Clann Choinnich" ] ) is a Scottish clan, traditionally associated with Kintail and lands in Ross-shire in the Scottish Highlands.  Traditional genealogies trace the ancestors of the Mackenzie chiefs to the 12th-century.  However, the earliest Mackenzie chief recorded by contemporary evidence is Alexander Mackenzie of Kintail who died some time after 1471.  Traditionally, during the Wars of Scottish Independence, the Mackenzies supported Robert the Bruce, but feuded with the Earls of Ross in the latter part of the 14th-century.  During the 15th and 16th-centuries the Mackenzies feuded with the neighboring clans of Munro and MacDonald.  In the 17th-century the Mackenzie chief was made Earl of Seaforth in the peerage of Scotland.  During the Scottish Civil War of the 17th-century the Mackenzies largely supported the Royalists.  During the Jacobite rising of 1715 the chief and clan of Mackenzie supported the Jacobite cause.  However, during the Jacobite rising of 1745 the clan was divided with the chief, Kenneth Mackenzie, Lord Fortrose, supporting the British-Hanoverian Government and his relative, George Mackenzie, 3rd Earl of Cromartie, supporting the Jacobites.
