“Happy HAIMoween get ready for our new song thats a HAIMMMMMMMMbop TOMORROW xoxo HAIMson,” reads the caption.
Hanson (not Haimson) responded to the jam session with their own tweet: “HAIMSON is finally a reality. Guess we know our Halloween costumes! #brothersandsisters”
Along with being a fun celebration of the holiday, the Haim post also teases a new song arriving on Wednesday, which they’ve been hinting at for the past week or so. The band posted on October 21st, “We’re about to release the most haim haimy haim song ever written, cool?”
Given that it is the “most haim haimy haim” song, in their words, the new song is likely to be an original track and not a Hanson (Haimson) cover.
Last month, the trio of sisters appeared on BBC Radio 1’s Live Lounge and performed a cover of Lil Nas X’s “Panini,” mashing it up with Nirvana’s “In Bloom,” which the former song interpolates. This past summer, they released a new single, “Summer Girl,” and collaborated on the Charli XCX track “Warm” for her album Charli.
