yep, Mountain Dog....that was one of the highlights of my TV watching career...He was introduced, and the camera focused on a totally black stage....then a lone spotlight slowly came up with Mason sitting on a tall stool..he began clapping in a slow, forceful rhythm, like a chain gang holler or something, and proceed to sing/chant...

THEM TOAD SUCKERS
(Mason Williams)

"How about them toad suckers? Ain't they clods?
Sittin' there suckin' them green toady frogs.
Suckin' them hop-toads, suckin' them chunkers,
Suckin them leapy types, suckin' them plunkers.

Look at them toad suckers. Ain't they snappy?
Suckin' them bog-frogs sure makes 'em happy.
Them huggermugger toad suckers, way down south,
Stickin' them sucky toads in they mouth!
How to be a toad sucker? No way to duck it.
Gittchyseff a toad, rare back and suck it!"

....and then the spotlight dimmed again, leaving the stage dark.

On the record,(which I am looking at as I type), he has little intros to each 'them' song, with a homey explanation about each. I am sure that when I saw it on TV there was NO introduction..(perhaps he did it more than once). I remember sitting there stunned as that spotlight dimmed....The record is called "The Mason Williams Listening Matter" Everest 3265...it says he was the head writer on the Smothers Brothers show in 67-68.The record has a date of April 11, 1969 on it....

(he also sang what he called his attempt at country music on this record..."You Done Stompt on my Heart"

All the 'Them' songs were short things, like Haiku...same rhythm, same length...
