Yeah, the show was excellent. It was a re-run from Labor Day 2003, but it was a fantastic appearance by Noel. I hadn't seen it until yesterday, so I'm glad they reaired it.
I was impressed that he sang the Goodbye Song live. Often he'll have a prerecorded version play in order to preserve his voice while moving and dancing.
It was also touching to see John Ritter on the show. This would've been about ten days before his passing on September 11.
