Initially called the Graham Wright Band, they changed their name to reflect their heritage and the place where they hail from: Glengarry County, Ontario, Canada.
The band's original members were Graham Wright (lead vocals, guitars, tin whistle), Gaye Stuart "Ziggy" Leroux (vocals, drums, percussion, bodhran)he now has 2 kids and 4 grandkids , Ewen McIntosh (bass, vocals) and Derek MacGregor (highland pipes, shuttle pipes, tin whistle).
A permanent bassist, Nigel "Gibby" Bazinet, and permanent piper, James Libbey (highland pipes, small pipes, whistles, keyboards, spoons, trumpet), were found and added to the line-up.
In September 2005, Downing, Libbey and Bazinet left the Glengarry Bhoys to pursue other interests.
On October 26, 2007 it was reported that Graham Wright, co-founder and leader of The Glengarry Bhoys, had been experiencing serious medical problems and could no longer tour, resulting in the band disbanding.
