My personal interpretation for ukulele of the epic Dr. Horrible song:

Bad Horse Chorus Dr. Horrible’s Sing-along Blog Music by Jed Whedon and Joss Whedon Lyrics by Joss Whedon

    C          Am
Bad Horse, Bad Horse
    C          G
Bad Horse, Bad Horse

   C
He rides across the nation
    F               C
the Thoroughbred of Sin
   C                            Am   D7   G
He got the application that you just sent in
   C                    F               G
It needs evaluation, so let the games begin
G
A heinous crime, a show of force
G
A murder would be nice of course

    C          Am
Bad Horse, Bad Horse
    C           G
Bad Horse, he's bad

    C
The Evil League of Evil
   F             C
is watching so beware
    C                                   Am    D7 G
The grade that you receive will be your last, we swear
   C                              F                  G
so make the Bad Horse gleeful, or he'll make you his mare
G
You've saddled up, there's no recourse
G
It's "Heigh-ho Silver"
G6          C
Signed, Bad Horse
