well the song is kinda complicated to tab
I still tried


intro:
+4 +5 -5 +5 +4 +5 +4 +5 -5 +5 +4 +5

 -4  +5 +5  +5  -4   -4  -4    +5    +5 +5 +5
Clue number one was when you knocked on my door
 +5    -5   -5  +5  -4   +5   -5  -5   -5
Clue number two was the look that you wore
 +5    -5  -5  +5  -4 -4 +5  -5     -5  +6
That's when I knew it was a pretty good sign
 +5   -5  -5   -5   -4   -5 -5  +5   +5+5 -4 +4
That something was wrong up on cloud number nine

Bridge:

+7    +7 +7  +7  -7  -7 -6  -6  -6    +6  +6  -5-5+5
Well it's a long way up and we won't come down tonight

 +7  +7 +7-7   -6   +6  +6   +6  -6   +6    -5
Well it maybe wrong but baby it sure feels right

Chorus:
+4  +4   -4  +5 +5  +4 +4   -4   +5   +5
And the moon is up and the stars are bright
+5   +5 -5    -5   +5 -4 +5 -5 -5
And whatever comes gonna be alright
 -5    -5 +5  +5   -4  +4  -3
Cause tonight you will be mine
-4 -5 -5    +5 -4  +4
Up on cloud number nine

(repeat)
And there ain't no place that I rather be

And we can't go back but you're here with me

Yeah the weather is really fine

Up on cloud number nine
