C             E   F                      G
Beware of the man who only shows you the best bits
C             E    F                  G
Beware of the band who type out their set lists
Am                          G
Sometimes instead of Arthur Lee
Am                          G
I'd much prefer some Arthur Lowe
C                  E
And with you by my side
F                 G
I would aspire to ascend
C                       E
Such heights where we'd find
F                        G
Tears and laughter cease to matter
Am                          G
And we'd be pleasantly surprised
Am            D7    G
By our annual water bill

C                 E          Am       F
I'm an early 'til late, indispensable mate
       D7        G        C
Of the bloke who does the PA
C               E           Am         F
I can lend or offend, I can mend and befriend
     D7          G      C  
As I help to set up the PA
     D7          G      C
As I help to set up the PA

C                    E
I found myself being sued
F                   G
By the firm Moore O'Ferrall
C                  E
I'd sprayed a graffito onto
F            G
One of their hoardings
Am                     G 
It was for Monsters of Rock
Am                                 D7 G
And I'd sprayed "In Church Hall if wet"

C                    E
They were sealing my fate
Am                     F
When I said "But I'm a mate
       D7        G        C
Of the bloke who does the PA"
C             E              Am        F
And the magistrate, he was a mate of a mate
       D7             G      C  
Of the bloke who sets up the PA
       D7             G      C
Of the bloke who sets up the PA
So throw it out of court

Thanks to oily_stage for his submission which got me started - I think this
is a bit more complete.
The only thing I'm missing is the chord played quickly between "Of the bloke
who does the PA" and its repeat, but you can play the song without it.  Let
me know if you can figure out what the chord is!
