I've seen nothing but 'wrong' tabs all over the internet.
so i did my own. this is right.
Listen to the song to get the strumming pattern down.
here is the best way i could think to describe it on paper: 

Intro:
Am          F           G           Am
00xxxx00xxxx00xxxx00xxxx00xxxx00xxxx00xxxx00xxxx

Verse:
Am                 F
   Did you see the lights
           G        Am
   As they fell all around you
Am                  F
   Did you hear the music
      G                Am
   A serenade from the stars

Am                 F   
   Wake up, wake up
        G           Am  
   Wake up and look around you
Am               F
   We're lost in space
           G           Am
   And the time is our own

Chorus:
G        Dm        Am        Am
   Whoaaaaaaaaaaaaahoooooooooooooooo
G        Dm        Am        F        G        Am
   Whoaaaaaaaaaaaaahooooooooooooooooooooooooooo~ooooooo
Am       F         G         Am
Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh


Verse:
Am                  F
   Did you feel the wind
         G        Am
   As it blew all around you
Am                  F
   Did you feel the love
        G          Am
   That was in the air

Am                 F
   Wake up, wake up
        G           Am
   Wake up and look around you
Am               F
   We're lost in space
           G           Am
   And the time is our own

Chorus:
G        Dm        Am        Am
   Whoaaaaaaaaaaaaahoooooooooooooooo
G        Dm        Am        F        G        Am
   Whoaaaaaaaaaaaaahooooooooooooooooooooooooooo~ooooooo
Am       F         G         Am
Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Verse:
Am               F
   The sun comes up
          G          Am   
   And it shines all around you
Am                F
   You're lost in space
           G             Am
   And the earth is your home


Ending Chorus:
G         Dm         Am         Am
   Whoaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
