"Interesting article.
ha bloddy ha,since when has Madam Bonaparte,been a reel,its a set dance played as a hornpipe,whoever wrote this is an ignoramus."

Just because the article has an error does not mean the article is not interesting or have a useful point to make. You may not agree with it. I am not entirely sure about what the article is saying, but the author still has an interesting point to make. IMHO.

On your point about Madame Bonaparte, to quote from Michael Raven's book "One Thousand English Country Dance Tunes" on Hornpipes and Reels

"...Hornpipe and reel melodies are especially fluid in their application...By simply varying the tempo and lilt, the same tune can be made to serve both dances..."
