Intro: F# G# C# A# (4x)

Verse 1:
                  F#                G#
Now you said that all would be just fine 
                F#                G#
And I know that changes come with time
          F#              G#                 F#       G#
Still sometimes I don't want the times to change

Pre-Chorus
           F#                   G# 
And I know tomorrow you'll be gone
           A#                  G#
So I know tomorrow will move on
       F#         G#           A#       G#  
But maybe part of us will stay the same


Chorus:
       C#
Don't fall asleep
         F#
We don't want to miss a moment
         A#                 G#                F#
'Cause tonight might be the best night of our lives
      C#
Don't close your eyes
         F#   
We could stay right here forever
         A#                 G#                F#       G#
'Cause tonight might be the best night of our lives

F# G# C# A#


Verse 2:
                  F#                    G#
I know sometimes I fight to keep things right
                 F#                  G#
Fighting ends up such a waste of time
    F#                  G#              F#      G#   
The time will spend the time we have right now

Pre-Chorus:
                 F#               G# 
Feeling like we don't know what's to come
              A#m                 G#
We'll be thinking where we first begun
       F#        G#             A#        G#
And trying to re-live it all somehow

Chorus

Interlude: 

C# C  G# A#

C# C  G# F#

Bridge: (sorry I couldn't figure out this part)
                           
We think we're headed somewhere
                             
Don't say goodbye tonight
                                
But we're not going nowhere
                
So don't say goodbye
       
Goodbye

Chorus

Outro: (Plays like Chorus)

Tonight might be the best night

Tonight might be the best night

Tonight might be the best night of our lives

F# G# C# A#  (4x)
