SUMMERTIME, SUMMERTIME
Sherman Feller, Tom Jameson
As sung by The Jamies, 1958.

It's summertime, summertime, sum-sum-summertime,
Summertime, summertime, sum-sum-summertime,
Summertime, summertime, sum-sum-summertime,
Summertime, summertime, sum-sum-summertime,
Summertime.

Well, shut [or "shuck" or "chuck"] them books and throw'm away.
Say goodbye to dull school days.
Look alive and change your ways.
It's summertime.

Well, no more studyin' history,
And no more reading geography,
And no more dull geometry,
Because it's summertime.

It's time to head straight for the Mills.*
It's time to live and have some thrills.
Come along and have a ball,
A regular free-for-all.

Well, are you comin' or are you ain't?
You slowpokes are my one complaint.
Hurry up before I faint.
It's summertime.

Well, I'm so happy that I could flip.
Oh, how I'd love to take a trip!
I'm sorry, teacher, but zip your lip
Because it's summertime.

It's time to head straight for the Mills.
It's time to live and have some thrills.
Come along and have a ball,
A regular free-for-all.

Well, we'll go swimmin' every day;
No time to work, just time to play.
If your folks complain, just say
It's summertime.

And every night we'll have a dance,
'Cause what's a vacation without romance?
Oh man, this jive has me in a trance
Because it's summertime.

It's time to head straight for the Mills.
It's time to live and have some thrills.
Come along and have a ball,
A regular free-for-all.

It's summertime.

It's summertime, summertime, sum-sum-summertime,
Summertime, summertime, sum-sum-summertime,
Summertime, summertime, sum-sum-summertime,
Summertime, summertime, sum-sum-summertime,
Summertime.

It's summertime.

[*Several online sources have it "them hills" but I don't believe it. I'm guessing "the Mills" is a reference to some locally famous hot spot.]
