Twelve Bar Blues is a formula used over and over:

The 12-bar blues chord progression is the basis of thousands of songs, not only formally identified blues songs such as "St. Louis Blues", "Shake, Rattle and Roll" and "Hound Dog", but also gospel songs, such as "I'm So Glad (Jesus Lifted Me)", jazz classics like "Flying Home" and "Night Train", pop and rock songs, including Glenn Miller's "In the Mood", The Beatles' "Why Don't We Do It In The Road?", and The Clash's "Should I Stay or Should I Go", Top 40 hits like Fabian's "Turn Me Loose", "At the Hop" by Danny and the Juniors, and the "Theme from Batman". The vast majority of boogie woogie compositions are 12-bar blues, as are many instrumentals, such as "Rumble" and "Honky Tonk".
