been racking my brains a bit all I can remember is like you say the first line was 
Hang down your head Tom Dooley 
Hang down your head and cry 
Wigan might have got to Wembley
but for Mickey's try 
and the next two lines were
He scored it in the corner 
The best try of his life 
after that I don't know. two many years of supping common has taken it's toll and the mind's gone blank sorry
