This is my first tab, and I just did this from ear, but I think it's pretty close. Enjoy!

                                   
Is there such a thing as too much of a good thing?
                     I ask myself that everyday
That is until the [bad word]          And the sun has gone away to sleep
                                Then there's only one thing on my mind (good time)

                                That's right, me and my baby love Saturday nights
               Saturday nights (saturday)
                        Yeah me and my baby love Saturday nights
               Saturday nights (saturday)

                With the dancin', and the singin'
                      Like the weekdays never happened
            I could be, I should be
Dancin' right now
                          'Cause me and my baby love Saturday nights

                      The talk of the town is where we're headin' next
                             'Cause everywhere we go is the best (the very very best)
It doesn't matter [bad word] But we're pretty [bad word]                  For you to have a round (a round a round a round)

                      And me and my baby love Saturday nights

               Here we go!

My baby and I my baby and I

We're goin' dancin' tonight

The dull [bad word] of the work week 
Gets me feelin' down
                          Misery and sorrow follow us around
But when that music hits in
And the band starts to play
That means you better
       Amaj7   
Get out of our way!

                         'Cause me and my baby love Saturday nights
               Saturday nights (Saturday)
                        Yeah, me and my baby love Saturday nights
               Saturday nights (Saturday)

[Acapella]                   
Me and my baby love Saturday nights

Saturday nights (Saturday)

Me. And. My. Baby. Love. Love. Saturday.
