Found it! and am now risking imprisonment...

Number 1 all-time worst song: MacArthur Park

Second place: Yummy, Yummy, Yummy, I've go love in my tummy

Strong third: You're Having My Baby.

Honorable Mentions:

Honey

Lay, Lady, Lay

Achy Breaky Heart

In the Ghetto, Watching Scotty Grow, Baby Don't get Hooked on Me

Stairway to Heaven

I Shot the Sheriff

Drifting from the folk theme, but there's the list. Peter, could you lead us in a hearty round of Kumbaya?... The axis seems tilted.

Have a great one!
