POW

Pow
I got-cha
Caught you with your funk down
Pow
I got-cha
So never let your guard down
Pow
I got-cha
I caught you with your funk down
Pow
I got-cha, and someone told the whole town
What did you expect
Ah, maybe you thought we was gonna sing a little classical a cappella
Something like ah
La. La, La, La. La. La. La
La, La. La, La. La
La, La
What did you expect
Ah, maybe you thought we was gonna play a
Little Chopin, Beethoven or Bach
What did you expect
Maybe you thought
I was gonna sing a little country funk
Like Ah
(Yodel)
Pow
I got-cha
I caught you with your funk down
Pow
I got-cha
So never let your guard down
Pow
I got-cha
I caught you with your funk down
Pow
I got-cha
And someone told the whole town
You should try your best
To keep your funkyness
So next time won't catch you
You'll catch someone else too
