After The Afterparty (SOPHIE Demo) is an unreleased demo of the song After the Afterparty by Charli XCX. This is a demo that greatly differs from the released version, being shorter, lacking the bridge and the featured artist’s verse (the released version features rapper Lil Yatchy), and has a very different production.

The track was released as the lead single for her now scrapped third album, XCX World, which was canceled after multiple delays and leaks.
