and repeat as many times as necessary.

ok, sorry for the confusing structure, but ill try to explain how this works.
the intro that you play four times goes under the guitar, as with the F to Fm.
the C A D and G parts you can improvise with the C and A being one measure and D and G 
two,
although the second measure of the G (that i've tabbed out) is the same as what the 
does at that time.
once again, sorry for the messy tab, but hopefully you get the idea of it.
