1. "Tush" is Yiddish slang for "butt" derived from תחת (taḥath) or "underneath". None of the members of ZZ Top are Jewish but bass player Dusty Hill told Spin Magazine "Tush" had double meaning when he was growing up in The Lone Star State.
"It meant what it means in New York. Tush is also like plush, very lavish, very luxurious. So it depended on how you used it. If somebody said, "That's a tush car,' you knew they weren't talking about the rear and of the car. That's like saying, 'That's a cherry short.' But tush as in 'That's a nice tush on that girl,' that's definitely the same as the Yiddish word. I don't know how we got it in Dallas. All it could have took was one guy moving down from New York."
2. Guitarist Billy Gibbons, one of the great car and guitar collectors, says the name comes from "Tush Hog" by fellow Texan Roy"Treat Me Right" Head.
3. When the band played George W Bush's inauguration party in 2001, they considered changing the lyrics to "Bush". They didn't. After all they would have had to sing "I said, Lord, take me downtown/ I'm just lookin' for some Bush"
4. After debuting at #79 the week of July 19, "Tush" peaked at #20 on the Billboard Hot 100 the week of September 6 1975. This is the first Top 40 for ZZ Top and helped propel the album Fandango! into the Top 10
