The first funeral service for Cooke was held on December 18, 1964, at A. R. Leak Funeral Home in Chicago; 200,000 fans lined up for more than four city blocks to view his body. Afterward, his body was flown back to Los Angeles for a second service, at the Mount Sinai Baptist Church on December 19, which included a much-heralded performance of "The Angels Keep Watching Over Me" by Ray Charles, who stood in for a grief-stricken Bessie Griffin. Cooke was interred at Forest Lawn Memorial Park Cemetery in Glendale, California.
Two singles and an album were released in the month after his death. One of the singles, "Shake", reached the top ten of both the pop and R&B charts. The B-side, "A Change Is Gonna Come", is considered a classic protest song from the era of the Civil Rights Movement. It was a Top 40 pop hit and a top 10 R&B hit. The album, also titled Shake, reached the number one spot for R&B albums.
Bertha Franklin said she received numerous death threats after shooting Cooke. She left her position at the Hacienda Motel and did not publicly disclose where she had moved. After being cleared by the coroner's jury, she sued Cooke's estate, citing physical injuries and mental anguish suffered as a result of Cooke's attack. Her lawsuit sought $200,000 in compensatory and punitive damages. Barbara Womack countersued Franklin on behalf of the estate, seeking $7,000 in damages to cover Cooke's funeral expenses. Elisa Boyer provided testimony in support of Franklin in the case. In 1967, a jury ruled in favor of Franklin on both counts, awarding her $30,000 in damages.
