I suppose all the old hands have departed the RT now? 

 

Anyway, to the song. If the lyrics were being written line by line, that line of the song would be all on it's own line. As the line is sung, there's a slight hesitation before "turns" like this:-

 

"And the world  turns"

I'm trying to remember more clues. I keep getting crossed lines with Andy Williams:-

Don't look so sad, I know it's over
But life goes on and this old world will keep on turnin'



It's life Jim, but not as WE know it.
Live long and prosper.
