The Spirit of '69 is a phrase used by apolitical or Anti-racist Skinheads to remind other Skinheads of the subculture's heyday in 1969 when ska music was at its most popular, and as a reminder of the cult's multicultural Jamaican and British working class roots.
It is also the name of a book published in the early 1990's by the author George Marshall, a former Glasgow skinhead.
