I was searching for this for a while; then from listening and watching
videos,think I've got it. The strumming pattern's fairly straight
forward once you listen to it, so I'll just put the chords & intro.

A5 *:  -0-7-7-6-0-0-
B5 :  -x-2-4-2-4-2-
C#5 : -x-4-6-6-5-4-
F#5 :  -2-4-4-5-2-2-
Ab5 :  -4-6-6-5-4-4-


** [ B5 -> C#5 ]
e----------------------4---------- | 
B----------------------5---------- | 
G----------------------6---------- | 
D----------------------6---------- |       x2
A--------2/4----4------4---------- | 
E--------------------------------- | 


INTRO:

Play the second one as a passing chords from the first to the last.
               E5 *            E5 *           A5 *
e--------------0--------------0--------------0-------------- |

(part of) CHORUS:

B5             Ab5
You can dance, you can jive, you're
C#5                     F#5
having the time of your life
E5              A5 *                            E5
See that girl, watch that scene, diggin' the Dancing Queen



VERSE

E5                                   A5 *
Friday night and the lights are low
E5                               C#5
Looking out for the place to go
B5
Where they play the right music, getting in the swing
                 **
You come in to look for a king
E5                       A5 *
Anybody could be that guy
E5                               C#5
Night is young and the music's high
B5
With a bit of rock music, everything is fine
               **
You're in the mood for a dance
              E5                  A5
And when you get the chance...


CHORUS
             E5             A5 *                       E5        A5 *
You are the Dancing Queen, young and sweet, only seventeen
E5              A5 *                     E5                   A5 *
Dancing Queen, feel the beat from the tambourine, oh yeah
B5             Ab5
You can dance, you can jive, you're
C#5                     F#5
having the time of your life
E5              A5 *                            E5
See that girl, watch that scene, diggin' the Dancing Queen


VERSE (same chords as above)

You're a teaser, you turn 'em on
Leave them burning and then you're gone
Looking out for another, anyone will do
You're in the mood for a dance
And when you get the chance...


CHORUS (same as above)

You are the Dancing Queen, young and sweet, only seventeen
Dancing Queen, feel the beat from the tambourine, oh yeah
You can dance, you can jive, yo-ooooooooooou're
[just strum chords once, play slower]
having the time of your life
Yeah see that girl, watch that scene, diggin' the dancing queen.

[End on E]
