As always you are in the right Richard. fiddle di dee and fiddle di doh are in so many ways totally unreconcileable.

Personally I live in hope that Paul Simon will nick Buster the Line Dancing Dog like he nicked Scarborough Fair off Elza's Dad, and then the whole world will be dancing Busters Boneseach - the official Buster the Line dancing Dog line dance. Though Tex from Stockport who devised this dance warns that it is fraught with danger for beginners.

Who knows perhaps Dylan will write a variant

If you travel in the North Country fair
Where the winds hit heavy on Wigan Pier
Remember me to Buster the Line dancing dog
For he is prettier than a picture by Van Gog
