If I got down on my knees and I pleaded with you
        G#m 
If I crossed a million oceans just to be with you
           C#m           F#
Would you ever let me down?


       B
If I climbed the highest mountain just to hold you tight

Would you ever let me down?

that you let me down

Would you ever fool around

          B                        Eb5       G#m
Well I'm sorry if it sounds kinda bad, just that
C#m
Worried, cuz' I'm so worried
                F#
that you let me down

Chorus

          B                       Eb5       G#m

Worried, cuz' I'm so worried
