Ron Kersey

Tyrone Garfield Kersey (April 7, 1949 – January 25, 2005), known as Ron "Have Mercy" Kersey, was an American keyboardist, songwriter, producer and arranger most known for writing the music to "Disco Inferno" by The Trammps.

Kersey was born in Philadelphia, Pennsylvania. He attended and graduated from Edison High School where he sang in the glee club and played football. He was a lifelong football fan and followed the Philadelphia Eagles. Kersey served in the United States Air Force from 1967 through 1972. While in the service he often played piano and keyboards at the local boards. There is where he gained the nickname "have mercy". It was the name the patrons would scream at him as he played because they loved his funky rhythms. Upon returning to Philadelphia, he re-acquainted himself with his longtime friend and musician Norman Harris. Norman was instrumental in Kersey becoming a studio musician at Sigma Sound Studios. He later became a member of the disco band The Trammps. Kersey did not like the constant travel so he decided to quit the band and concentrate on producing and writing. In 1978 he received a Grammy Award as producer for the soundtrack to Saturday Night Fever which included "Disco Inferno", which he co-wrote with Leroy Green. He was also a member of MFSB and the Salsoul Orchestra. He moved to Los Angeles in 1980 and continued his career as a sought after studio musician, producer and songwriter.

In addition to co-writing "Disco Inferno", Kersey produced or co-wrote songs that reached the top 20 for other artists. He produced Stephanie Mills' "I Have Learned to Respect the Power of Love" which charted at number one for two weeks on the R&B chart. It was Mills' first number one single and would prove to be her most successful single. Ron Kersey was also the producer for her next single "If I Were Your Woman", a cover of the Gladys Knight & the Pips hit that reached number one for three weeks on the R&B chart for Stephanie Mills. In addition, he co-wrote "Every Drop of Your Love" for Stacy Lattisaw that peaked at number 8 on the R&B chart. He co-wrote the slow jam "Send for Me" with Alex Brown peaking at number 17 on the R&B chart. Kersey also appears on many Philadelphia International Records as a studio musician most notably Teddy by Teddy Pendergrass, Unmistakably Lou by Lou Rawls and Message in the Music by The O'Jays.

Kersey suffered a stroke in 1997 and died in Philadelphia in 2005.
