Chuck Willis had more than a half-dozen top ten singles on the R&B chart beginning in 1952 before his cover of the old standard C. C. Rider reached #1 on the R&B chart and #12 on the Hot 100 in 1957.
The original a-Side of his next hit record, Hang Up My Rock And Roll Shoes charted, but only reached #9 on the R&B chart and #24 on the Hot 100 in 1958. Shortly after that single was released, Chuck died while undergoing surgery for ulcers, after which What Am I Living For began getting more airplay. That side of the single climbed up the charts and reached #9 on the Hot 100 and #1 on the R&B chart.
