Cale, whose best-known songs became hits for Eric Clapton with “After Midnight” and Lynyrd Skynyrd with “Call Me the Breeze,” has died. He was 74.

His best songs like “After Midnight,” ”Cocaine” and “Call Me the Breeze” were towering hits — for other artists. Eric Clapton took “After Midnight” and “Cocaine” and turned them into the kind of hard-party anthems that defined rock for a long period of time. And Lynyrd Skynyrd took the easy-shuffling “Breeze” and supercharged it with a three-guitar attack that made it a hit.
