I never suggested, of course, that tardiest and laziest are synonomous. Apart from the internal rhyme mentioned earlier, I'm quite happy with "laziest" as a narrator's gently sardonic comment on the idea of driving a car through the wilderness.
More generally: as an unaccompanied singer with a very mixed but largely traditional or traditional-style repertoire, I typically find that, as I learn songs, they tend to morph slightly in my head for a variety of reasons. If a song has a very standardised set of words and a static presentation style, I find I'm not likely to sing it - regularly, at least. That said, I may happily join in in with someone elses singing of it where appropriate!

p.s. Or, as a well known female Irish singer remarked once: "Martin - you just collect oddities of song!"!
p.p.s. I continue to be fascinated by the "Ads by Google" generated by our threads. The current one is offering me two possibilities of a Northwest Passage voyage in 2008. Clearly, the organisers have great fate in global warning!
