The Countdown has started and by now you should all know your words off by heart. Time to see if you know when to come in on each song - below are all the backing tracks for the songs. If you can't work out when to come in, check the training tracks below, count the intro, then come back here and try again. It's really important you learn your introductions well, so lot's of practice over the next week and a bit please! Concert is on Wednesday 17th August.
