"Barbecue" is one of those words with strangely inconsistent spelling. According to the record company's own web site, the album title is spelled "Barbecue King" but the song title is spelled "Barbeque King."

Anyway, here's what I transcribed from a sound sample at Yahoo! Shopping - Music:

The barbecue king is comin' to town.
With his shiny pants, well, he looks like a clown,
And he'll cook your barbecue anyway you please.
