Solid Potato Salad - Ross Sisters 1944

I originally became obsessed with this video featuring the Ross Sisters a few years ago - I watched it several times a day for quite a while and "had" to decipher the lyrics. There's something about this: the goofy song, the stage setting, the vintage costumes - not to mention the amazing contortions that had me enthralled. My sister-in-law gave me the VHS of the movie; it's from Broadway Rhythm (it's not released on DVD - go figure). I was curious to see how this clip fit in to a movie but the video got buried and I forgot about it. Last week a friend posted it on Facebook and again I can't get it out of my head! Now to track down my copy of the movie.
Here's my best attempt at lyrics - can anyone help me fix them?
Root toot tooo yew dut
Root toot tooo yew dut
Da doo day
Root toot tooo yew dut
Roo doo loo dooo loo dut bah doodle bay boys
Solid potato salad That's solid salad, Jack
Hit your _____ with
Solid potato salad, boys
Take my plate, Fill it up, And bring it right back
Solid potato salad
And lets have no Yak Yak
Solid potato salad, boys
Take my plate, fill it up, And bring it right back
The farmer said to the spud (solid solid salad days)
Your skin looks slightly pallid (solid solid salad days)
So I'll dig you later bud (solid solid salad days)
For some solid potato salad hoy hoy
Solid potato salad
It's a groovy, movie salad, Jack
Solid potato salad, boys

Dat do dat do dat do day
Bring it back!
And speaking of "bring it back" What say we re-introduce "solid" into the vernacular? You know . . . as in "that's sooo SOLID".
"Awesome" and "You rock" are totally over-used these days. We need this groovy word back as another way to say "excellent". Who's with me?
