Think in terms of Stress. If you can say Rangers Celtic in time with the music it is definately in 4/4.And its a Ree; If Polka Polka fits better its in 2/4. If you find you are saying Liverpool Everton,this is a Jig in 6/8 and if you find its Liverpool Everton Manchester,Its one of these 9/8 Slip jig thingies. And DONT ask about 5/4 - Its Bloody Awful.
