Well... - ( and probably I shouldnt have started )- but, due to a complete lack of capability in this area, i tried all the obvious ones....
"He's bloody great, is David Mund-y..." - to the tune of Manic Monday :The Bangles
"We'll tell you why, .. we love Dave Mundy" - to the tune of Why i dont like Mondays : Boomtown Rats
" Mundy, David Mundy, .." - to the tune of Sunday, Bloody Sunday :U2
And ,
"Well, he's our Dave Mundy... I ask you is he any good?"" - To the tune of the Bradman song : traditional.
...but couldnt get past the 1st line on any of them.!
So decided to go back to my tractors and leave it in the hands of experts like you, Jordo....
