Tongland is a local nickname for the area of Calton, Glasgow controlled in the 1960s by a violent Scottish teenage gang called the Tongs. The Tongs financed themselves using a Protection racket, levying money on shops within their territory, and they marked that territory out in graffiti with their slogan "Tongs Ya Bass".
The origin of their name has varied legends, one legend is told thus: "In the 1960s, in an East-End cinema near Fielden Street, some of the local Calton gang with some leader called McCabe were watching a film, The Terror of the Tongs. about the Chinese secret society...
"...when McCabe shouted out 'Tongs ya Bas' for the first time. McCabe consequently renamed himself Terror McCabe"
This is a legend and may not be a historical event. The name Tongs may have a combined origin:
Calton in the 19th century was ruled by the brutal "San Toys" gang, and that name was written with wildly varied misspellings: 'San Toi' in the 1930s
"Ya bass" is generally taken as the Glasgow slang for "you bastard", though it has been proposed it could be the Gaelic war cry aigh bas meaning "battle and die". Another Glasgow gang slogan was "Spur ya Bass". "Tongs Ya Bass" arguably became Glasgow's unofficial motto in the 1960s and 1970s.
Tongland appears in Gillies MacKinnon's 1995 movie Small Faces, set in the 1960s. The Tongs and other gangs' power over the area and their decline in the 1970s is described in Janey Godley's 2005 autobiography, Handstands in the Dark.
