The Tennessee Salute by Richard M. "Pek" Gunn was adopted by Tennessee in 1975 as a bicentennial march song.

Tennessee, Oh How I love you
with your fertile rolling plain
Tennessee your lakes are playgrounds
where the water skiers sway

Purple tinted hills and mountains
Touring over fields of grain
To the speeding boats that pull them
Through the misty silvery spray

Smoke and steam from busy factories
Rising upward in the air
Trout and brim and bass and croppie
Finest in the U.S.A.

From the smoky mountains to Mississippi
Happiness is everywhere
When you go a-fishin’
Catch instead of wishing’
H’rah for good ole Tennessee

Oh how I love you
There is none that is above you
You are on the move

Tennessee is on the double
With a minimum of trouble
No one can do prove

Tennessee is on good footing
Industy is really putting
Hard times on the run

Everything that’s done and said
puts Good ole Tennessee ahead
We’ll all join in the fun
