I've got that Cub Scout spirit
Up in my head,
Up in my head,
Up in my head,
I've got that Cub Scout Spirit 
Up in my head,
Up in my head to stay.

On successive verses, replace 
"Up in my head" with:
       Deep in my heart,
       Down in my feet,
       All over me,
in turn. 
On the last verse sing all four.

This was John Willett's fall  
back  song for reluctant 
singers and Scouts and 
Scouters from Pensylvania 
at Jamboree 2001 
(It is a polka after all.)
