Can't have originated in Kent in 1954 as it was common currency in the North East of England in the late 40s (as far back as I can remember). In the West Country, according to legend, a white rabbit is some sort of ghost that floats about in pop videos. Seth Lakeman wrote a song about said albino creature which somebody at Smoothops thought was a traditional piece and classified it as such in the Folk Awards. If white bunnies were ever lucky, they sure as hell ain't now.
