This two-and-a-half-minute track is autobiographical. According to Sham 69: History, Discography And Biography (published circa 1978), Sham 69 were lined up for a short US tour, but lead vocalist Jimmy Pursey got involved in an incident at the Vortex which led to him being arrested. In turn this led to the American Embassy refusing him a visa, so with guitarist Dave Parsons he wrote this charming ditty, which ends with the words: "stick America up your arse."
In contrast, if you listen closely you may hear something resembling "The Star Spangled Banner" in the melody at one point.
"No Entry" was released on the Polydor label in October 1978 as the B-side of "Hurry Up Harry."
