Seeing as the midfield one went off on a tangent to another tune, here's another go at one to "Proud Mary".

He spent a lot of time in Melbourne
Then a little while up in old Hong Kong
But he never saw - the good side of the A League
Until he came to coach in Wellington.
Proud Ernie something something
Proud Merrick something something
Something - something - something on a something.

(Best I could come up with for the last bit was:
Proud Ernie you're still peaking
Proud Merrick keep on speaking
Scottish, Scottish, Scottish on the sideline.

But I'm sure someone else can think of something much better.)
