It was natural for Michael to assume that you were talking about Irish-style sessions, that being what people usually mean when they use that ignorant and patronising "diddly dee" cliché.

If you want a real discussion, say what you mean; tell us what you play yourself, and why you think yourself superior to these unnamed people you took a dislike to. If you just want to arse about with online translation routines, then you are several years too late to be amusing.
