I haven't got the hang of the usual notation, but on a scale from the G below middle C to the g and a above middle C, and in a polka rhythm starting on the upbeat it would be something like this:

As         I         came         home         one         eve        ning
G        C        C        E        G        C        C

like         a         de        cent         wo        man should
E        G        C        G        C        E        g

The         rogue   he         foll        owed         af        ter         me,
g        a        a        F        a        g        g        e

as         I         knew         the         rogue         he         would
g        g        F        E        D        C        B        

He         was         an         old         rogue,        a         bold rogue,
D        G        B        C        E        G        C    E        

a         rogue         of         low         de        gree
G        C        G        C        E        g

Come                 lis        ten         and         I'll         tell         you
g                a        a        F        a        g        E

what         the         rogue         he         done         to         me
E        g        F        D        B        G        C
