The songs that comprise Primus’ 1991 album, Sailing the Seas of Cheese, are loaded with topics that remain uncommon in the rock format — a warning against “a hammerhead shark, nose hairs and flatus” (“Here Come the Bastards”), a studly feline (“Tommy the Cat”) and eating taco-flavored Doritos on a boat (“Fish On”). And “Those Damn Blue Collar Tweekers” can also be filed under this category. “A tweaker is someone who is strung out on methyl amphetamines, otherwise known as crank,” Les Claypool told Rolling Stone. “There’s a reference in there to a guy who hung Sheetrock, and that’s how he got through the day. He’d snort up speed to keep up with the younger guys.” When “Tweekers” was performed at Woodstock ’94, Claypool inserted in a bit of “The Star Spangled Banner” on his bass, mid-song, as a sideways Hendrix tribute.
