WHAT!!!! Another bob Marley thread

Had to start this.....I think the song sounded dodgy and dull purely because people were singing the song and getting the timing wrong, I'd be trying to sing it in time and tune whilst some other bloke would start singin the next line immediately.....
I personally think that we should sing the tune in between each line as it will give better atmosphere and keep everyone in timing. Anyone agree?.......don't worry du du du du du about a thing etc etc
