'Ring of Fire' (1963) is one of Johnny Cash’s biggest hits, co-written by his wife-to-be June Carter. Its lyrics use fire as a metaphor for an intense love affair ('I fell into a burning ring of fire'). Notably, the song features a brassy mariachi horn line (Cash first claimed he hated the trumpets) that helped propel it beyond country radio. It topped the country charts and became a crossover hit. The song’s catchy, bold imagery has given it life in pop culture; for instance, it was even humorously referenced on *The Simpsons*, showing its enduring appeal.
