Ми любим ніч
Unknown authorship. It uses the Doo-Wop chord progression which means that it's probably based on a Doo-Wop song. We'll likely never know for sure the original song it was based on as there are many songs with melodies close enough that it might be a modification of any of those (e.g. "Runaround Sue" - Dion), but after listening to Doo-Wop playlists for hours, "Never" by The Earls was by far the most similar. If you find a closer match, please edit!
