In February of 1978, Blondie's "Denis" entered the U.K. Top 50 where it would climb all the way up to Number 2, prevented from hitting the toppermost of the poppermost by Kate Bush's "Wuthering Heights". "Denis" is actually a cover version of the 1963 Randy and the Rainbows Top 10 hit "Denise". Blondie keeps the Buddy Holly-ish sound but adds some of Debbie Harry's "pidgen french" lines.
