In August 1985, "Bigmouth Strikes Again" and "Some Girls Are Bigger Than Others" were recorded at RAK Studios in London, along with the B-sides to "The Boy with the Thorn in His Side", "Asleep" and "Rubber Ring". Kirsty MacColl sang a backing vocal for "Bigmouth Strikes Again" but it was considered "really weird" by Marr, and was replaced with a sped-up vocal by Morrissey in the final mix, for which he is credited as Ann Coates on the sleeve of "The Queen Is Dead". "Some Girls Are Bigger Than Others" includes a false fade near the start, intended by Street to give the impression of a door closing and opening again. During the same session, a first version of "Never Had No One Ever" was recorded.
