Tube Snake Boogie

My van’s radio has a display that tells me the name of the song playing and who wrote it and I’ve just started to pay attention to the names of the songs and I’ve found something interesting. I’ve been singing songs wrong for years, especially ZZ Top. “Push”, is actually “Tush”, and “Two-Three Boogie” is actually “Tube Snake Boogie”. Well…that’s a totally different cogitation to the songs—much dirtier than my innocent and incorrect versions. I’ve come to the conclusion that ZZ Top are dirty old men, plain and simple. I’ve also started wondering what other songs am I singing wrong? Could “Excuse me while I kiss this guy” really be “Excuse me while I kiss the sky”? I must investigate this some more.
