"Grandma Got Run Over by a Reindeer" is a novelty Christmas song. Written by Randy Brooks, the song was originally performed by the husband-and-wife duo of Elmo and Patsy Trigg Shropshire in 1979.
The first wide release of the song was in Canada in 1982 by The Irish Rovers, released on the album, It Was a Night Like This. Their signature version rose to #20 on the RPM charts within a week of its release. The single became a seasonal hit, first on country stations, then on Top 40 stations, and today remains a 'seasonal holiday anthem'. The song was also released on the Rovers' 1999 album Songs of Christmas.
