Quirky and peculiar: Unusual customs snapped in the '70s by photographer Homer Sykes

From gurning and dunting, to skipping and barrel-wrestling - these strange and unusual traditions are marked annually in towns and villages. Forty years ago, in the pre-mobile phone era - when flared trousers and glam-rock ruled - Homer Sykes travelled across the country to capture special moments from these uniquely British celebrations.

The images feature in Homer Sykes' republished 1977 book - Once a Year - from Dewi Lewis Publishing.

Music by Slade, Thin Lizzy, 10CC, David Essex and Lindisfarne.
