This was written in 1955, [Bo Diddley's](https://www.youtube.com/watch?v=SaC5ZKRjLUM) R&B classic number of the same name, which was later an American Top 20 hit for [The Yardbirds](https://www.youtube.com/watch?v=JAdCePtwoW4), as well as Chicago. Chicago's cover arrangement features an extended percussion and drum section with a total run time of 7 minutes and 40 seconds, and is based around the distortion-heavy blues-rock guitar of Terry Kath, the drumming of Danny Seraphine, the bass of Peter Cetera, the soaring Hammond organ of Robert Lamm and the horn players periodically switching over to auxiliary percussion instruments, such as claves, cowbell, maracas, and tambourine. Kath, Cetera and Lamm each sing a verse apiece (not singing the lyrics as they were originally written, but as they misheard and/or revised them), preluding Seraphine's extended drum solo before a return to the second and third verses with the horn section and choruses that bring the song to a climactic drum roll, and finally leading into a guitar solo to bring the song to a dramatic close. It is unclear if the maracas were performed by Lamm or overdubbed by Seraphine during his drum solo. "Now, I got to keep my image While I'm standing on the floor If I drop upon my knees It's just to keep her on my nose" Well, well, that's certainly a mental image, isn't it?
