I remember down in Houston, we were puttin' on a show
When some cowboy in the back stood up and yelled, "Hot Nachos!"

The story:

I always sang it like that, because I assumed that at this concert that the song described there was a vendor selling hot nachos, and that this cowboy just wanted to have some. It makes perfect sense to me. My sister heard me singing it that way and laughed at me a lot! I didn't believe her, but then I looked it up and found out that she was right.
