I'd suggest we throw out TWO words from our (poets) vocabulary,
1) Competition, and
2) Performance
replacing them with, Engaging and Entertaining.
The old masters didn't have the competitions we do now. They had to submit to a publisher (The Bulletin being one), there they had to follow the rules of grammar and punctuation otherwise no publication = no money.
I hate to admit it, but sometimes I write crap! Just because we write in metered rhyming verse doesn't mean we're all a Lawson, MacKellar or a C.J.
I'm looking at Graham's stuff, it's meticulously crafted and are great performance pieces without the need to change one iota. It's engaging AND entertaining.
I contrast his works with Neil MacArthur's. By his own admission he pushes the rhyme and pulls the metre, yet it's engaging AND entertaining.
Putting our works into a bigger 'pot' (such as a
competition 
), we sometimes find what we deem to be excellent is only mediochre. It's good to be humbled.
If we try and push the rhyme and pull the metre through laziness, it shows. And no matter how good the concept is, if we fail in telling it in an engaging and entertaining manner, we fail. Also, if our subject matter is poor then we've failed again.
I'd suggest (Your Honour) that there is no difference between "Written" and "Performance" verse.
