A Vancouver* radio station said in a now-deleted tweet, "Hold onto your bobble heads, @arcadefire have promised us a new tune on Friday!"
Did someone tweet out information they weren't supposed to share? Sure sounds that way!
In the meantime, here's old Arcade Fire to hold you over. If you don't recognize the song title, give it a listen anyway. I'll bet you know the song.
*Vancouver, I will be in you next week! #vacation
