"Knuckle Sandwich Nancy" is a song by English rock band Slade, released by Cheapskate in 1981 as the lead single from their tenth studio album, Till Deaf Do Us Part.

[1] Speaking to The New Standard in 1981, lead vocalist Noddy Holder revealed of the song's lyrics, "It's about a bird we used to know years ago whose answer to everything was to knock fellows about.

"[2] "Knuckle Sandwich Nancy" was released as a single in the wake of the band's commercial comeback after a well-received performance at the Reading Festival in 1980.

They once again began to receive attention in the British music press and scored their first top 10 hit in over five years with "We'll Bring the House Down" in early 1981.

[3] "Knuckle Sandwich Nancy" was released on 15 May 1981 on the independent label Cheapskate, which was operated by bassist Jim Lea, his brother Frank and Slade's manager Chas Chandler.
