Hi, I think it's easier to play with these chords, because you can just take a regular 
E, then "bar chord" A and B (which are close on the fretboard).

At "wild thing, I think I looooove you" just be lazy and switch between regular E and 
hitting the same 3 strings without taking any chord at all with your left hand...

E         A B A
Wild thing
             E         A B A
you make my heart sing
         E            A B A
you make everything     Groovy
       E          A B A
I said wild thing...
