Dursley

A 1920's dance that, for a short time, rivalled the Charlston. Unfortunately, due to a high number of sprained ankles, the Dursley faded into obscurity. It enjoyed a short revival in 1933 but the cost of the reinforced ankle boots (required to avoid said ankle problems) made it prohibitive for the working classes.
In 1975, the music for the Dursley was rediscovered by Richard O'Brien and incorporated into his musical 'The Rocky Horror Picture Show'. He changed the name of the dance and re-wrote some of the choreography but the tune stayed the same.
"Let's do the Dursley again" bacame the world-wide hit "Let's do the Time Warp again".

Findo Gask

Findo Gask was a hobbit who left the stiflingly boring Shire and went to seek his fortune among the southron lands. While the minor northern fracas between some jumped-up hedge-wizards obsessed with an overvalued ring passed by, he was by turns a trader, thief, bandit, horse-dealer, merchant, beggar, mercenary, spy, and many other things, told in a series of richly textured fantasy adventure novels which Tolkien never got around to writing.

South Wonston is quite near where I live and reminds me of stuff I'd rather not be reminded of. Can someone do it - quick - and put another name in there? Please :-)

South Wonston was, in fact, the stiflingly boring Shire village from which Findo Gask (qv.) shook off the dust from his heels and never looked back. He would never, ever, speak of the place afterwards, and grew murderously violent with anyone who did. In his declining years, settled in a land where nobody had ever heard of hobbits and taking to drink, he was liable to accost anyone of short stature and hairy feet with the words, "Ye a Wunster, eh? eh? Are yez? ARE YEZ?" and attempt to beat them senseless with a stout walking stick.
