Tim Minchin - F Sharp chords

I've been having a little problem recently
          Bb         A            Dm
Which is quite disturbing musically
          Bb      A       Dm
Involving a semi-tonal discrepancy
          Bb      A     Dm
Vocally and Instrumentally
Gm          A


You see musicians of different varieties
        Bb           A         Dm
Prefer playing in particular keys
        Bb        A          Dm
And singers too treat preferentially
    Bb           A     Dm
Those notes they tackle more proficiently
      Gm                     A


Now, you, don't have to be a member of MENSA
                Bb           A         Dm
To understand the depth of my dilemma
   Gm                         A
The two elements of me favour two different keys
        Bb          Dm Gm                   Dm
Thus the rift between my fingers and my Tenor

I love nothing more than playing songs in F
Bb                       F
It warms the very cockles of my heart
   Gm                        A
The problem is that F can leave me vocally bereft, you see
    Bb                             F
I like playing in F Major, but I like singing in...
       E7           A7           
F Sharp.... F Sharp.... F Sharp...
Dm          Dm          Dm


I refuse to be beholden to my hands
Bb                         F
I don't see why my Larynx should give in to their demand
Gm                               A
I will not be forced to compromise my art
Bb                                 F
So I'll keep playing in F Major, and singing in...
E7           A7 
F Sharp... F Sharp... F Sharp...
Dm         Dm         Dm


I'll keep playing in F Major, but I'll keep singing in F Sharp!!!!
          Gm         C7                                F
