"Mercy, Mercy, Mercy" is a jazz song written by Joe Zawinul in 1966 for Cannonball Adderley and which appears on Adderley's album Mercy, Mercy, Mercy! Live at "The Club". The song is the title track of the album and became a surprise hit in February 1967. "Mercy, Mercy, Mercy" went to no. 2 on the Soul chart and no. 11 on the Billboard Hot 100 chart.
The original version was performed by: Cannonball Adderley (alto saxophone), Nat Adderley (cornet), Joe Zawinul (piano, electric piano), Victor Gaskin (bass) and Roy McCurdy (drums). The theme of the song is performed by Zawinul on a Wurlitzer electric piano previously used by Ray Charles.
The first part of the theme is played twice and is completely made of notes from the major pentatonic scale of the first degree.
The tune is in the key of B-flat major and has a 20-bar structure with four distinct sections. The chord progression is mainly made of dominant-seventh chords on the first, fourth and fifth degrees, giving the song a bluesy feeling although it does not follow a typical blues progression. The subdominant (IV) chord in the beginning section emphasizes this bluesy feeling. In the second section, the tonic chord alternates with a second-inversion subdominant chord, creating a parallel to the I-IV-V progression (in which the tonic moves to the subdominant).
Marlena Shaw recorded a version which peaked at no. 58 on the Billboard Hot 100 on the week of April 1, 1967. Shaw's version had lyrics by Gail Fisher and her husband Vincent L. Levy, credited as "G. Levy" and "V. Levy." It also peaked at no. 66 on the Cash Box Top 100 Singles chart on the week ending April 8.
"Mercy, Mercy, Mercy" has been re-recorded numerous times, most notably by the Buckinghams, who reached no. 5 in August 1967, adding lyrics to the tune which were written by Johnny âÂÂGuitarâ Watson & Larry Williams in Feb, 1967.
