Haim - who are set to release an album next month - share a producer with Arctic Monkeys, and it was Ford who suggested that the three Californian sisters come into the studio and record backing vocals for the Monkeys' fifth LP.
Speaking to NME, Ford said he played Haim the Monkeys song 'Do I Wanna Know?' whilst they were still recording, and suggested they lay down the track's backing vocals. "They loved it. So me and the Arctics had the discussion, 'Should we get some real girls in?".
However, Haim had to turn the offer down, as they were too busy trying to complete their own album, 'Days Are Gone' - out September 30. "We tried to push things around to make it work," bass player Este Haim told NME. "But when it came down to it, we had to finish our record... That would have been our biggest dream come true - to sing on an Arctic Monkeys record... It was one of the most painful calls to say no. Maybe the worst day of my life."
