Well Jerry, we could refer back to that thread,"Songs I wish I had written...". OK, so I am just being mischievous...
To your question. I might want to talk about Bob Dylan's "Desolation Row." It has one of the best opening lines ever. "They're selling post cards of the hanging," is such an evocative image for chaos, perversity, corruption and despair all at the same time. And then the song goes into verse after verse of graphic metaphor. I don't think songs of that sort existed before. The author has stepped onto new ground for a popular songwriter. The rhymes are sharp and the metre is precise. It is also proof that a complex, long song can remain interesting. Most of us are better off not even attempting that sort of thing, but it is a stunning example of what a master of the craft can achieve.
