The singer behind “Lightnin’ Strikes” and other hits, died after a “brief illness” his family said in an Instagram post. KDKA Radio confirmed Christie’s passing with his management team.

The singer-songwriter reached No. 1 on the Billboard Hot 100 in 1966 with his hit single “Lightnin’ Strikes.” His song, “Rhapsody in the Rain” also made the top 20 later that year.
