yes, it has merit,it gets the audience participating,its even better,if several people shout it one after another[a sort of echo effect],even better if there is someone called mcintyre in the audience he/she can then get up and say,yes what do you want, the singer then says apint for everyone in the house,the whole song then goes off on a diversionary trail for a few minutes,and everyone has a good time,then everyones goes back to the old dun cow again.
