Elvis's last song "All Shook Up" was written by both Presley and songwriter Paul Terry King. The two performed the song together in private. The song was never published or released before Elvis's drug overdose death in 1977. Presley's ability to woo a crowd with hip gyrations and blue black hair was made him a rock icon for a lifetime. "All Shook Up" depicted his life as it was before his death. His rockabilly infused, yet R&B sound is classic and remains some of the best music ever produced, written and performed.
