Del Amitri is a Scottish alternative rock band, formed in Glasgow, Scotland in 1983.
 The band grew out of Justin Currie's Jordanhill College School band and came together after a teenaged Currie placed an advertisement in the window of a music store asking for people who could play to contact him.
 The band was formed with the original line-up of Currie (bass and vocals), Iain Harvie (lead guitar), Bryan Tolland (guitar) and Paul Tyagi (drums).
 Currie and Harvie were the only members of the band to remain present throughout its history.
 They were also the main songwriters of the group.

Mount Currie is a small, mostly First Nations, community in British Columbia, 164 kilometres north-west of Vancouver and 40 kilometres north-west of Whistler along Highway 99.
 "The Mount Currie settlement and mountain were named after Scottish settler John Currie, who located to Quebec in 1851.
 After failure as a gold seeker in California and the Cariboo, Currie turned to ranching and finally settled near Pemberton with his Lillooet Indian wife in 1885."
 The area is traditional territory of the Lil'wat, a subgroup of the St'at'imc people who with the communities of Skatin, Samahquam and Xa'xtsa (Port Douglas) to the south comprise the Lower St'at'imc or Lower Lillooet.
 The Mount Currie Indian Reserve hosts most of the population of Mount Currie, who are known as the Lil'wat, their name for the spot, but west of the reserve there are non-native farms, industrial sites and tourist resorts, and on the mountain shoulder immediately north of the reserve is Owl Creek, the site of the original Catholic mission school which drew the Lil'wat from their former homebase at Pemberton Meadows so as to be close to their children.
 Owl Creek today is the name of a modern subdivision of mostly non-natives, though Owl Creek remains on the rail crossing on the CNR just outside the reserve.
Justin Robert Currie (born 11 December 1964) is a Scottish singer and songwriter, best known as a founding member of the band Del Amitri and, along with Iain Harvie, is one of only two members of the group to be present throughout its entire existence.
