According to guitarist Billy Gibbons, they got the idea for the title from a song called "Tush Hog" by the Texas musician Roy Head, released in 1967.
The band pointed out to anyone who may have been offended that this song is gender neutral - it can be sung by a man or woman. Their point was proven in 1981 when the group Girlschool covered it on their album Hit & Run.
ZZ Top considered changing the lyrics and performing this as "Bush" when they were asked to play for fellow Texan George W. Bush at his inauguration party in 2001. They decided against it.
Lyrics
I been up, I been down.
Take my word, my way around.
I ain't askin' for much.
I said, Lord, take me downtown,
I'm just lookin' for some tush.
I been bad, I been good,
Dallas, Texas, Hollywood.
I ain't askin' for much.
I said, Lord, take me downtown,
I'm just lookin' for some tush.
Take me back way back home,
not by myself, not alone.
I ain't askin' for much.
I said, Lord, take me downtown,
I'm just lookin' for some tush.
