It's a pretty tune, but what made 'More than words' so good, imo, was the harmony.
For Chris, I would try something like 'Beth' by Kiss or some other 'love' song that a hard rock group sang. Perhaps the people voting for Chris would forgive him for doing some sappy love song, but if it was originally done by a rocker. 'Wonderful Tonight' by Clapton could be a good choice, but that may be too slow.
You never know though, perhaps Chris has a penchant for something really goofy like 'Close to you' by the Carpenters.
