Beck solo project. Between 23 September and 9 October, the new configuration toured Britain with the Rolling Stones for a dozen shows. During this time, the Yardbirds also recorded "Happenings Ten Years Time Ago" and were filmed performing an updated version of "The Train Kept A-Rollin, titled "Stroll On", for their appearance in Michelangelo Antonioni's film Blowup (1966). Composition After Samwell-Smith's departure, Yardbirds' singer Keith Relf and drummer Jim McCarty spent more time together and began exploring shared interests in popular mysticism and reincarnation. While the two were at Relf's home, they started with an idea for a song with a theme of "being reborn, living before" and déjà vu. Relf's lyrics, as heard in the finished recording, include: "It seems to me I've been here before, the sounds I heard and the sights I saw, was it real or was it in my dreams, I need to know what it all means". Later, Page became involved in the recording studio: In another interview, Page explained that some of the material he contributed to the Yardbirds was actually developed while he was still a studio guitarist and asserts that "Happenings Ten Years Time Ago" was "basically my thing". "Happenings Ten Years Time Ago" is composed of four main sections: vocal verses with the main rhythmic accompaniment, chorus, an instrumental middle, and an instrumental closing. Musical notation shows the key of E minor, with a moderate tempo of 127 beats per minute in 4/4 or common time. The song begins with a four-bar instrumental opening, then settles into the main rhythm, which music educator William Echard describes as "distorted punctuating chords, a repeated descending chromatic line, and drums with strong accents on every [quarter note] beat", along with electric bass. The accompaniment continues through Relf's first verses, then transitions to a Gregorian chant-inspired interlude. McCarty adds a harmony to Relf's vocal while single guitar chords are played, which suggest "tones of the ritualistic, epic, and ancient" (Echard). This soon gives way to the chorus, which includes repeating two-note figures on guitar, that "underscores the ominous, tense mood" (Echard). After cycling through more verse and chorus sections, the first instrumental section begins. Group chronicler Greg Russo describes that it "took off on an astounding tangent, with Page's guitar imitating a police siren before guitar explosions and a searing Beck solo worked around Jeff's Cockney-influenced recitation".
