Lyrics:

Oh, Chicken, Chicken, you can't roost too high for me
Chicken, Chicken, come on outta' that tree
Chicken, Chicken, Chicken, you can't roost too high for me
C is the way we begin
H the next letter in
I am the third
C for to season your bird
K is to fill him in
E I'm near the end
C-H-I-C-K-E-N
That's the way to spell chicken
