I'm also chiming in with agreement, except I'd use, instead of 'classic,' the word 'unimaginative.'

A decent rule of thumb, which is of course wrong in any number of cases, is that, if you're trying to add something to a poem or set of lyrics, the worst way to do so when you've already got something that works and feels whole is to add length to it. And, sadly, a lot of people have a tendency to ruin something that just came out by forcing on additions with the thinking mind.
