Joe, the lyrics Jed Marum posted way upthread mostly agree with what I hear when I listen to the Spoonful recording, a few typos aside. What I transcribed is this:

JUG BAND MUSIC
(John Sebastian)

I was down in Savannah
Eatin' cream and bananas
When the heat just made me faint
I began to get crosseyed
I thought I was lost
I'd begun to see things as they ain't
As the relatives gathered to see what's the matter
The doctor came to see was I dyin'
But the doctor said give him jug band music,
It seems to make him feel just fine

I was told a little tale about a skinny as a rail
Eight foot cowboy with a headache
He was hung up in the desert swattin' rats
And tryin' ta get a drink of water with his knees a'gettin' mud-caked
And I'll tell you in a sentence how he stumbled into Memphis Tennessee
Hardly crawlin', lookin' dust-baked
We gave 'im little water; a little bit of wine
He opened up his eyes but they didn't seem to shine
And the doctor said give him jug band music
It seems to make him feel just fine

So if you ever get sickly
Get Sis to run quickly to the dusty closet shelf
And pull down a washboard; and play a guitar chord
And do a little do it yourself
Call on your neighbors to put down their labors
And come and play the hardware in time
'Cause the doctor said give him jug band music
It seems to make him feel just fine

I was floatin' in the ocean
Greased with suntan lotion
When I got wiped out by a beach boy
He was surfin' when he hit me but jumped off his board to get me
And he dragged me by the armpit like a child's toy
As we staggered into land with all the waiters eatin' sandwiches
And tried to mooch a towel from the hoi polloi
He emptied out his eardrums; I emptied out mine
And everybody knows that the very last line is
The doctor said give him jug band music
It seems to make him feel just fine
And the doctor said give him jug band music
It seems to make him feel just fine

I'm a little worried about the phrase "hardware in time", but if it isn't that then I don't know what it should be. I also worry about "armpit" in the last stanza, and wonder whether it shouldn't be "arm just".

There are all kinds of crazy mishearings on the various internet lyric sites.
