A couple hours' fun at nine

I'll be out the month of September
But I'll be back as soon as I can
With a schedule to make
And some tests I must take
I need time, at least that's the plan

But I'll still be playing tonight
And it's not like I'll really be gone
You all can still get
A pretty good set
From a DJ I know I can count on.

Has it been 10 years? at nine

Summer's near its end, at last
It's getting kind of cool now.
Time to enjoy all kinds of tunes
From that club called Pow Wow.
