I actually wrote some I use when trying out PA systems

When I need to try out the PA
I have to have something to say
So what do I do
I just say one two
Not exactly original eh?


When we're trying out the sound system
Our engineer needs some assistin'
To try out the mic
We could say what we like
But one-two,one-two takes some resistin'

Why do I just say one two, one two, one two (fading echo effect!)
When anything else would do, would do, would do
I know it sounds boring
But please stop your snoring
I'm doing it just for the crew, the crew, the crew,the crew.......
