This is not a double/previous post. I actually wanted to post about the fantastic Beachcombing's Bizarre History Blog which has not been featured here before and chose the Katzenclavier [sic] post to introduce it. The fact that there has been a recent post about Katzenklavier has no bearing on my post. It may have some relevance to the previous post but as rivenwanderer said in the comments "the Strange History blog is fantastic". Maybe I should have just posted the general URL of the site but I thought I'd point out a particular post that I found interesting and let everyone explore for themselves as rivenwanderer and I'm sure many others would have. Une leçon apprise. Minor gripe - the 'original post' didn't have katzenklavier in the tags [not that that would have helped considering my cut and paste misspelling, but still].
