This is an oldie but goodie.  easy to play.
G
Here's my story its sad but true
Em
about a girl that I once knew
C
she took my love and ran around 
D
with every single guy in town

Then do the hep hep's and go into the song with these four chords played in loop.
G
I should'a known it from the very start 
Em
this girl'd leave me with a broken heart
C
Listen people when I'm tellin' you
D
keep away from a Runaround Sue.

do the woh woah woaaah's 

always the same four chords.  If you want you can do the Dsus thing each time
you play the D chord at the end of the loop.

I missed her lips and the smile on her face
the touch of her hand and that girl's warm embrace
if you don't wanna cry like I do 
Keep away from the Runaround Sue

She likes to travel around 
Yeah she's got a love that'll put you down
People let me put you right 
Cause Sue goes out with other guys yeah

The moral and the story from a guy who knows
I fell in love and my love still grows 
ask any fool that she ever knew 
I'd keep away from a runaround Sue

then the woah's again
