"Cornerstone" is a song by the English indie rock band Arctic Monkeys, released as the second single from their third album Humbug.

The track is said to be about a boy who goes around to different social pubs and bars in the hopes of finding a woman who looks like his ex-girlfriend to re-live or subsequently continue their relationship; going as far as to ask the question: "Please, can I call you her name?

"[4] In each one of the verses, Alex Turner references different made-up clubs (the Battleship, Rusty Hook, Parrot's Beak; most likely to be hypothetically found in the England area) and how he finds look alikes to this lover visiting them, but once he asks if they would be okay with being a replacement to the girlfriend, they reject him along with his proposal.

[5] He then comes across his old lover's sister in the Cornerstone (a real counselling centre found Sheffield[6]) during the last verse, where he successfully "restarts" his past romance.

[7] (I saw your sister in the Cornerstone on the phone to the middleman/And when I saw that she was on her own/I thought she might understand that she was close/Well, you couldn't get much closer/She said "I'm really not supposed to, but yes/You can call me anything you want") The music video for the single debuted on Channel 4 in the UK on 15 October 2009.
