"Happenings Ten Years Time Ago" is a song by the English group the Yardbirds. Written and recorded in 1966, it is considered one of their most progressive works. The song was the group's first to feature the dual-lead guitar line-up of Jeff Beck and Jimmy Page. The two contribute an array of guitar parts during the instrumental sections, described as "a full-on six-string apocalypse". Lyrically, it deals with notions of past life and déjà vu.
