A truly sick and twisted new filksong

See if you can follow this:
First there was "The Wild Rover," music & lyrics by Trad. & Anon.;

Then there was "I'm Looking Over A Four-Leaf Clover," lyrics by Mort Dixon & music by Harry Woods (1927);

Then came "I'm Looking Over My Dead Dog Rover," to the tune of "Clover", parody lyrics by Hank, Stu, Dave & Hank (1978);

All of which congealed in my brain while doing a mindless, repetitive task at work today to form THIS...

( A new filk! )
